[lazarus] htmlhelp1 example patch
Checking the htmlhelp1.lpi example I found an error, I don't know how to
apply a patch so I tried to create one.
I attached it.
Once applied the patch also the oncreate event should be removed by the
form.
Without this patch the example does not work, applying it the example
works both on windows and linux.
let me know if the patch is correct or if there are other ways to apply
and create patches.

[lazarus] checkoptions bug
Dear all,
if I build a simple console application, just created by lazarus and I
run it using the -help option I get this error:
project1 -help
exception at :
Invalid option at position 1: "e".
Both in windows and linux. The result is given by:
ErrorMsg:=CheckOptions('h','help');
While HasOption('h','help') interpret correctly the long option -help.
Best regards,
Andrea

cthreads,

Andrea Mauri wrote: Ok, a brief explanation. I am developing a software for molecular descriptors calculation. For every molecules I have to calculate thousands of descriptors. These descriptors are divided in blocks. During the calculation I would like to store the calculated descriptors in a database, embedded, I chose firebird but actually I am working on a not embedded IB6 database. For every block I create a table, every table has tens of columns, each column is a molecular descriptor. All the fields are float. Every row is a molecule. I create the table at runtime. After the suggestions of raistware and bram I changed the tables structure using unique field names. Two create statements are at the bottom of this mail. There are more then 20 tables, every table with tens of columns. After the calculation I would like to show the calculated descriptors to the user. So I join the tables. If I join the empty tables TSQLquery works properly, if the tables are not empty I got the error: incorrect values within sqlda structure I get this error with TSQLquery but not using zeos component. With zeos components I have other problems (slowness and the obtained fields are not float). The query could be a query with a join of 20 or more tables.

[lazarus] read big file and store info
Dear all. I need to read big text file and store the starting position and length of blocks that are present in this file. I have text file with a tag that identifies the beginning of a text block (this tag in the example is "- start -") and a tag that identifies where my block finish (i.e. "- stop -"). I don't know how long these text blocks are, they could be also of one single line, and I don't know how many of these blocks there are in a single file, could be one or thousands. I would like to read my file one time and then store the start position and the length of every block in order to access rapidly and directly to each block. Once stored start and length I would like to read each block directly and store the text lines to a TStringList. These files could be huge ( 1 Gb) so I would like to read one time and then access directly to a defined block. i.e. my file are like this - start - first block of a lot of characters and a lot of lines - stop - - start - second block of a lot of characters and a lot of lines - stop - ... - start - n-th block of a lot of characters and a lot of lines - stop - Any suggestion? andrea _ To unsubscribe: mail [EMAIL PROTECTED] with "unsubscribe" as the Subject archives at http://www.lazarus.freepascal.org/mailarchives

By giving the order to compile, you implicitly give the order to save.
If I perform the same steps in Delphi when I close my project Delphi
asks me if I want to save my project and if I say 'no' when I open my
project again I have the first version of my project.
Delphi can compile from files kept in memory, Lazarus cannot.
My "problem" is, I have a big project, with many units, I make a lot
of modifications daily, I want to test if everything works as I
want, so I compile my project many times in a day.
I don't want that lazarus saves my project every time I compile it
and I don't want to make a manual backup of my project every time I
modify it. I want that lazarus saves my project only if I decide to
save it and not if I compile it.
That is not possible. If you don't save your changes, your unchanged
file will be compiled.
Is it not possible to have the same behavior as in Delphi?
At this moment, no.

Yes, it must do that, otherwise the compiler cannot compile it. The
compiler must access to the files on disk.
I open an existing project, I modify it, I compile it,
So all modifications are saved.
I close the project without saving it and saying to lazarus, when it
asks me, that I don't want to save.
The project is saved anyway with the modifications.
What modifications?
Lazarus last svn on winxp.
I'm doing something wrong?
I don't know.

Re: [lazarus] deploy an application
You can use 'ldd ', it will show you a list of all linked libraries. It depends on the LCL-Interface, you use. If you choosed GTK1, then the GTK1 libs are needed. Most of the libs listed there are on mostly all Linux distributations out there. I compiled my app on Fedora and tested on Ubuntu. After ldd myapp I obtained on Ubuntu that only one library was missing: libgdk_pixbuf.so.2 but I wasn't able to install with sudo apt-get install libgdk_pixbuf.so.2 it said that libgdk_pixbuf.so.2 doesn't exist. Finally I found libgdk-pixbuf2 and installed it. Now myapp works fine but if I check the dependencies with ldd it finds libgdk_pixbuf.so.2. Why? Which is the difference, why it said that libgdk_pixbuf.so.2 is missing but the only lib I can find is libgdk-pixbuf2? I would like to deploy only the binary file and not the source. Which is the best way in order to do that? RPM? Tarball? Both and more. A Debian-package would be also nice for Debian users and an Ebuild would be nice for Gentoo users. RPM is the prefered type for Red Hat and SuSE users. I will check for Debian and Gentoo. I have to deploy all the required libraries? The users can install the missing libraries by his own? Most package systems support dependency-lists. You can add the appropriate libs to this list. But if I make a tarball I have to put in the tarball also the appropriate libs or I can say in some way which libs are needed in order to run myapp? How can I use the tarball in order to write a Debian package or a Gentoo ebuild? thanks again. a. There is a tutorial where I can find this kind of information? I read "Deploy your application tutorial" but I didn't find any information about the required libraries if I decide that I don't want to use RPM. An on which Linux distribution works the RPM? RPM would work on allmost every Linux distribution, if the appropriate tools are installed there. But I would not install a RPM directly on my Gentoo system. I would extract the files and install them manually or write a simple ebuild for it. The best way I think should be a tarball. You could write then a Debian package or a Gentoo ebuild, which use this tarball to install your program. -- Albert

[lazarus] GLScene package
Hi to all, I've installed lazarus (SVN) on my Fedora Core 5 pc. I'm trying to install the GLScene package (I've already installed it on my windows 2000 pc). I found two problems, the first one is that in the cvs repository all the subdir included in the Source directory are in lowercase but GLScene package try to find them in the correspondent uppercase directory (Source/base (CVS dir) Source/Base (GLScene package dir). I changed the compiler options for GLScene package in order to look in the lowercase directories. Now the compilation of GLScene package works but when I rebuild the IDE it said fatal error can't find unit opengl1x. opengl1x is in the Source/base dir and this path is correctly set in the compiler options of the GLScene package. I tried to add this directory also in the compiler options of the IDE but it doesn't work, still the same error. I've already installed the opengl package of lazarus. What could be the problem?

Ok, I added Types in the uses units of Virtualtrees.pas and in Virtualstringtree.pas units and now lazarus compile correctly the virtualtreeview package. Thanks a lot, Andrea Vincent Snijders wrote: Andrea Mauri wrote: I downloaded the last lazarus SVN and the last CVS virtualtreeview.

Andrea TSize used to be in the LCLType unit, but since last night the LCL uses the TSize declaration from the types unit.

Re: [lazarus] VirtualTree
I have another problem with VirtualTreeView with the last SVN, lazarus
can't rebuild because in the VirtualTrees.pas it uses TSize that cannot
be found.

We commented it out to see if any 3rd party tool would use it. You just
found out.
And there should be a virtual method like ParentFontChanged providing the
same functionality.

So, what I have to do to make VirtualTreeView works properly?

[lazarus] lazarus components
In internet I found a lot of tutorial on how to write components in delphi. I found also a tutorial that explain how to convert delphi component for lazarus. I would like to try to write components with lazarus, there is a wiki page or a tutorial to do that? Can I follow the tutorial dedicated to delphi also for lazarus? Which are the main differences?

[lazarus] VirtualTree
Hi, I downloaded the last svn vesion of Lazarus (WinXP) with tortoisesvn. I've installed VirtaulTree in my Lazarus IDE some weeks ago, it worked but now it doesn't work, building Lazarus it says that CM_PARENTFONTCHANGE is not defined. I saw that in the vtheader.inc it VirtualTree uses CM_PARENTFONTCHANGE but it is commented in the lmessages.pp unit: //CM_PARENTFONTCHANGED= CM_BASE + 8; // LCL doesn't send or receive Anyone could help me?

A lot of command syntax error. Do you have Delphi installed? Looks like you are using Borland Make to compile Lazarus. Type just "make" on the command line to see what make you are using. You need to use the make program witch comes with Free Pascal.

[lazarus] Can't rebuild lazarus
I downloaded the last lazarus via svn. (Windows XP). I also installed fpc 2.0.2. Now I can't compile any projects (Can't find unit interfaces) I checked the fpc directory in the environment options and it is correct, also the fpc source. I also tried to rebuild lazarus but it gives me 1511 errors during make. I tried make clean all and it gives me 1511 error. A lot of command syntax error. What can I do to solve it? Thanks, Andrea

[lazarus] MAC address
I would like to convert a delphi/kylix project in lazarus project. In the kylix project there is also a function that checks the MAC address: ethernet:= 'eth0'; i:= socket(AF_INET, 2, 0) ; if not i < 0 then begin StrPLCopy(@f.ifrn_name, ethernet, IFNAMSIZ); if not ioctl(i,SIOCGIFHWADDR,@f) < 0 then begin m := @f.ifru_dstaddr.sa_data; // MAC FmtStr(MAC,'%.2x:%.2x:%.2x:%.2x:%.2x:%.2x', [Byte(m[0]), Byte(m[1]), Byte(m[2]), Byte(m[3]), Byte(m[4]), Byte(m[5])]); end; end; There is a way to do it also with lazarus/fpc?
