[fpc-pascal] Is there some reason why the linker cannot find crti.o, crtn.o etc?
These messages come up almost always when I compile a project: Warning: "crti.o" not found, this will probably cause a linking failure templateSys.lpr(39,1) Warning: "crtn.o" not found, this will probably cause a linking failure. On a 32bit system the files are located in /usr/lib/i386-gnu and /usr/lib/gcc/i686-linux-gnu find /usr/lib -type f -name crt* /usr/lib/i386-linux-gnu/crti.o /usr/lib/i386-linux-gnu/crtn.o /usr/lib/gcc/i686-linux-gnu/4.X/crtbegin.o /usr/lib/gcc/i686-linux-gnu/4.X/crtend.o I don't know if some of them are debug builds which may have other attributes which make them undetectable by the linker. Some of the errors may also be related to the gnu tools and not be FPC/Lazarus related. This issue bit me when I was trying to cross compile some synopse libraries (I have forgotten how I fixed it) and I want to know how it can be fixed permanently in my installations. -- Frank Church === http://devblog.brahmancreations.com ___ fpc-pascal maillist - fpc-pascal@lists.freepascal.org http://lists.freepascal.org/cgi-bin/mailman/listinfo/fpc-pascal

Re: [fpc-pascal] Help building FPC on armhf
I think I now remember having the same problem before, can you please try to build with "-O-" instead of -O2 ? In the past the compiler threw an exception in system.pas, perhaps it now displays an error message.

At least for debian the values for Floating point should be OK for the Wandboard: "Currently the Debian armhf port requires at least an ARMv7 CPU with Thumb-2 and VFP3D16."

Re: [fpc-pascal] Is there some reason why the linker cannot find crti.o, crtn.o etc?
In our previous episode, vfclists . said: > Warning: "crti.o" not found, this will probably cause a linking failure > templateSys.lpr(39,1) Warning: "crtn.o" not found, this will probably cause > a linking failure. Under Linux, the directory for those files is passed to FPC by a -Fl line in the fpc.cfg which is setup by the installer script (standalone pkg) or the distribution (in the case of a distribution package) Usually that installer calls fpcmkcfg which calls gcc with --print-libgcc-file-name to determine the location. This assumes everything is configured correctly when FPC was installed, if not, try rerunning fpcmkcfg or manually fixing fpc.cfg ___ fpc-pascal maillist - fpc-pascal@lists.freepascal.org http://lists.freepascal.org/cgi-bin/mailman/listinfo/fpc-pascal
[fpc-pascal] TDBF licensing
Hi, Am I correct in understanding that TDBF included with FPC is a LGPL licensed component, the one that doesn't have the static linking exception. So I can't use it in any commercial products or tools without being forced to release all my source code?

TDBF originally comes from http://sourceforge.net/projects/tdbf/ and is indeed distributed under the LGPL. > So I can't use it in any commercial products or tools without > being forced to release all my source code? It doesn't matter whether the products or tools are commercial or not. The LGPL means that if you link statically against TDBF, you have to provide (on request) the object files of your program to customers that bought the original tool so they can relink it against newer/modified versions of the TDBF code. There is no reason why you would ever have to release your own source code, except if you would start mixing your own source code into the TDBF units or so.
