Hi,
I am trying to find a solution to converting this macro:
#define msg(flags, ...) do { if (MSG_TEST(flags)) x_msg((flags), __VA_ARGS__); } while
(false)
Or this one:
#define msg(flags, args...) do { if (MSG_TEST(flags)) x_msg((flags), args); } while
(false)
To something that MSVC++ will allow to compile, currently it appears that cannot. I
will be happy to see someone with a solution to this...
(BTW, this code is taken from the OpenVPN project, which I am trying to build a MFC
based GUI for, open sourced of course)

Don't confuse between production code and customer code. Internal code (including all the examples you gave, which are good but few) can be production. There is ample anecdotal evidence of surveys done at software development conferences of how many programmers work on customer deliverables. The numbers usually quoted are in the range of 95% code written for internal consumption. Last time I personally was present when this kind of question was asked was at Go-Linux in spring. A speaker asked a big hall full of people who developed software for a living (a good portion of the audience raised hands) and then who wrote code sold to customers (2 or 3 hands). In every company I worked for internal scaffolding was done. Prototypes, demos, tons of debugging code and tools specific to the domain, research tools, simulators for hardware and software, independent implementations of different solutions only one of which ultimately became production, customization and fixing of existing software and libraries, throw-away code to try things out, you name it. A situation where you have tools that generate ready production code for you, verify it, generate automatic builds, testing, and all the rest of the scaffolding, sounds really exotic to me.

Hi,
I am trying to find a solution to converting this macro:
#define msg(flags, ...) do { if (MSG_TEST(flags))
x_msg((flags), __VA_ARGS__); } while (false)
Or this one:
#define msg(flags, args...) do { if (MSG_TEST(flags))

To something that MSVC++ will allow to compile, currently it
appears that cannot. I will be happy to see someone with a
solution to this...
(BTW, this code is taken from the OpenVPN project, which I am

To quote: The company I work for currently does not allow engineers access to code they have no business reading in the first place. Of course, a malicious programmer can always social engineer his way into getting access to the code. How is that contradiction? Does not allow != VP RD signs approval forms. When I need access to code X, I ask the person in charge of that for access, and he either gives it to me or not, based on the reasons I give him. If he doesn't, I either flog him with really long SATA cable or talk to his boss. The point I try to drive is, you don't need good reasons to compartmentalize. You need good reasons not to. I said nothing about compartmentalization, whatever meaning you care to put into the word. I remarked on the passage quoted above, saying that reasons to do that were few and far between. Well, most tools do exist (e.g. source control, automated testing, UML code generator) for 99.9% per cent of the companies, who deal mostly with standard software engineering. The other 0.1% may require exotic tools (e.g. I have no idea how to test VMWare without special tools). I am guessing wildly. It seems that your notion of standard software engineering differs from mine. I suspect you assign all the different things I did and all the things I am doing to 0.1% of exotic activities. Dealing with VMWare does not seem exotic at all to me... You misunderstood my example. I did not mean *using* VMWare, I meant *testing* VMWare (as the VMWare vendor). If you know how to reach a ratio of internal to customer code of more than 10:1 (apart from Excel macros), and produce decent customer code, would you consider sharing the insights? You seem to either be really amazed by what I said. People, am I the only one in the forum who thinks that most code written is production code? Don't confuse between production code and customer code. Internal code (including all the examples you gave, which are good but few) can be production. There is ample anecdotal evidence of surveys done at software development conferences of how many programmers work on customer deliverables. The numbers usually quoted are in the range of 95% code written for internal consumption. Last time I personally was present when this kind of question was asked was at Go-Linux in spring. A speaker asked a big hall full of people who developed software for a living (a good portion of the audience raised hands) and then who wrote code sold to customers (2 or 3 hands). I find it extremely hard to believe. I' think that the business model of the employers of those present at that Go-Linux is skewed in a sick, sick way (assuming open-source is still a long way from being profitable for any but a select few). Every single person in the my development group is developing code that is sold to customers. Previous jobs had roughly the same percentile of money-bringing people (surely all had 90% money earners). In every company I worked for internal scaffolding was done. Prototypes, demos, tons of debugging code and tools specific to the domain, research tools, simulators for hardware and software, independent implementations of different solutions only one of which ultimately became production, customization and fixing of existing software and libraries, throw-away code to try things out, you name it. A situation where you have tools that generate ready production code for you, verify it, generate automatic builds, testing, and all the rest of the scaffolding, sounds really exotic to me. To tersely comment on these long paragraphs: I never worked for companies who waste their resources writing prototypes and demos that never ended as production code. It's not that I select my jobs that way, it just never happened. I suspect such companies either have deep pockets to fund these activities, or they go under very fast. There are demos, there are prototypes, not every implementation is customer code, I'll grant you that. But, in a system with 7GB worth of code (the system I currently work on), with ~90% of it going to customers, there aren't ~70GB lines of internal code.

RE: Linux/UNIX/ISO VARARGS to MSVC++ ???
Hi,
Thank you for the answer, the problem with that solution or this that I found prior to
posting this message: http://www.codeproject.com/debug/location_trace.asp
Doesn't take into consideration the fact that MACROs are compile-time things,
consuming no CPU in run-time. So that solution becomes tricky as CPU time is consumed
while the original MACRO:
MSG_TEST(flags)
Consumes no CPU...
This is due to the fact that I cannot pre-evaluate the MSG_TEST(flags) part :(
I hope I made myself clear...
BTW:
#define MSG_TEST(flags) unsigned int)flags) M_DEBUG_LEVEL) x_debug_level ||

I would email him your file, so that he can see another example of the problem. Mine was with Hebrew quotes.

Re: Version control (was: Re: What's wrong with this code?)
I think this is exactly the price you pay when choosing these kind of tools, or more generally, doing in the unix way: You just take some overhead explicitly onto *your* head but you are left with very flexible, hence powerfull, set of tools, which can be combined in numerous ways to do just about any task you choose (in principle). you do not have *such* flexability, usually, in closed source (graphic?) application. this power lures in the command line land. Its raw power, but roughness in usage, against fixed (closed) methods/ways to use, but the ease of that usage.

I had all the packages for the HD installation on the /home partition. The installation went OK, except for the fact that when installing LiLo, there was an error that said somethin about that LiLo could be installed only on the MBR. Since that was my intention, I continued. After the reboot, I saw that LiLo did not see any changes that were done during the installation, and when trying to boot into mdk, the kernel paniced (no init found). I've used Knoppix to see what's going on, and I discovered that fdisk -l issues warning invalid flag 0x of partition table 5 will be corrected by (w)rite and it sees only the windows partition and hda1 which was left empty for future use.

Why do they need to be easily integratable? What if it will take your sysadmin a whole day to do this integration? And what if you pay a services company (like IBM previously mentioned in this thread) to provide you with a turnkey solution? Nobody said ever said that every user should need to install and configure free software on his/her own. You might ask, well, if it costs me money, why is the free-software solution any different from the propriatry one? Well, there's a big difference. The free software solution won't charge you by user (haven't you ever seen developers shout across the open space please log out of the version control software, I need a license!?). The free software solution will still be available when you decide to switch to a different platform, CPU, or operating system. If a bug in the program seriously annoys you, you can hire someone to fix it for you (with commercial software, you'll need to beg the manufacturer to fix it or give you partial sources.) Note, however, that some special scenarios - like 100 people working full-time on a single huge code - are simply not useful in the free software world, which is why you don't see free software catering to those needs. Also, free software tends to cater to the needs of people who write it (namely, developers) rather than managers and so on. The managers sometimes don't like it. For example, in a previous workplace I was asked to switch from Bugzilla to a commercial bug tracking software (that was integrated with the version control system).

RE: Linux/UNIX/ISO VARARGS to MSVC++ ???
Hi, I am not interested in a discussion on whether to use MFC or not, I just wanted to know whether MSVC++ supports VARARGS. If I can't see any other way, I will go and try another GUI creation environment, though I must say, I haven't been impressed with any of them, especially QT, in the aspects of easy development (Kdevelop and QTDeveloper are not so good as far as I can see).

RE: Version control (was: Re: What's wrong with this code?)
I agree with you. Though, what Rational did that make their ClearCase product relatively successful, is the relative ease with which you can script their products.

Nobody said ever said that every user should need to install and configure free software on his/her own. You might ask, well, if it costs me money, why is the free-software solution any different from the propriatry one? Well, there's a big difference. The free software solution won't charge you by user (haven't you ever seen developers shout across the open space please log out of the version control software, I need a license!?). The free software solution will still be available when you decide to switch to a different platform, CPU, or operating system. If a bug in the program seriously annoys you, you can hire someone to fix it for you (with commercial software, you'll need to beg the manufacturer to fix it or give you partial sources.) Note, however, that some special scenarios - like 100 people working full-time on a single huge code - are simply not useful in the free software world, which is why you don't see free software catering to those needs. Also, free software tends to cater to the needs of people who write it (namely, developers) rather than managers and so on. The managers sometimes don't like it.

I tend to agree - in the real world there is no magic.

This investment time is what the ads try to deceive us that can be saved - but this is rarer than promised (as always in advertisements and he real world...)
