This option makes a difference on the m68k, m88k, and the SPARC. Position-independent code requires special support, and therefore works only on certain machines. Essentially what this does is make libraries relocatable, the difference between -fpic and -fPIC being the size of the global offset table (and this difference is only on some archs). You may want to try with -fpic instead, since you're not using one of the arches specifically mentioned. Since vpopmail doesn't generate dynamic libraries this shouldn't really be making any difference. Doing it on 32bit won't cause any problems, as it has nothing to do with word size. Also, you'll want to be on the latest stable gcc release you can get your hands on, as the x86-64 target has been evolving fairly rapidly from what I can see with a little quick googling. Hope that helps, Nick
Re: [vchkpw] compile "vpopmail" with -fPIC on x86_64
hi marco i will most def. try that tonight. however i can only test on the production machine, as all my other test machines are 32bit Intels. I will let you know most def. ... should be another 2 hours or so till i can take it down again. the last time i tried to install courier-authlib and vpopmail on a amd64 was in january (the mail you've found in the archive). i've tried it again some minutes ago on my production machine (as you can try more or less without disturbing the normal users) and i've run again in the same problems: 1. compiled vpopmail with -fPIC 2. compiled courier-authlib with -fPIC the compilation of both of them worked just fine 3. started the installed authdaemon... already at the beginning i get the following: 12:30:54 pluto authdaemond: Installing libauthvchkpw 12:30:54 pluto authdaemond: /usr/local/libexec/courier-authlib/authdaemond: Symbol `read' causes overflow in R_X86_64_PC32 relocation 12:30:54 pluto authdaemond: /usr/local/libexec/courier-authlib/authdaemond: Symbol `__errno_location' causes overflow in R_X86_64_PC32 relocation 12:30:54 pluto authdaemond: /usr/local/libexec/courier-authlib/authdaemond: Symbol `__errno_location' causes overflow in R_X86_64_PC32 relocation 12:30:54 pluto authdaemond: Installation complete: authvchkpw if i try then to login with e.g. sqwebmail (5.0.1 compiled with -fPIC too) the authdaemon segfaults: 12:30:54 pluto kernel: authdaemond[966]: segfault at 2aab004016b0 rip 2aab004016b0 rsp 7fffcde8 error 14 i have no idea if this would be a problem of authdaemon or of the vpopmail libraries that the daemon uses? :-( up to now i haven't heard of anybody that has had success with courier-authlib & vpopmail on a amd64 architecture :-(( regards KoS

Re: [vchkpw] compile "vpopmail" with -fPIC on x86_64
Jeremy, this is a little off the main topic, but i was wondering .. what does the -fPIC do? what causes this "issue" ? good buddy of mine wrote & updates a QMAIL Install script ... does it all for you, including courier-IMAP or Bincc ... and he was wondering whether or not he shoudl include the -fPIC command when his script compiles vpopmail - whether this command will bomb & cause errors on 32bit systems. I will take the production server down in a little, and try to install vpopmail with fpic the way you suggested.

Jeremy, are you saying that one will have to run CFLAGS=-fPIC BEFORE the ./configure like Nick stated? so in essence i would run my configure as followed: #CFLAGS=-fPIC ./configure --enable-roaming-users=y --enable-logging=p --enable-qmaildir=/var/qmail I apologize in advance, I'm learning.

You put CFLAGS=-fPIC BEFORE the ./configure. This makes it an environment variable. You can find more out about environment variables in man bash, ksh, or whatever shell you use.
