[fpc-pascal] FPC 2.6.2 for DOS/Go32V2 FP.PAS cannot compile with GDB support

[Lubomír Čabla]

Attempt to compile IDE from snapshot with GDB:

FPC GO32V2 2.6.2 is installed in z:\pp
PATH contains Z:\pp\bin\go32v2

Instruction from Tomas Hajny does not work:

*creating directory "libgdb" next to "rtl", "ide" and "packages", unpacking*
*content of the downloaded file there and then compiling again using:*

*make clean rtl_all packages_all ide_all "OPT=-gl -O-"*

Ii fails with error message

on screen:

z:/pp/bin/go32v2/ld.exe: cannot find -lgdb
make.exe[3]: *** [fp.exe] Error 1
make.exe[2]: *** [buildfp] Error 2

So, I made this:

1. download source package 21.10.2013
   ftp://ftp.freepascal.org/pub/fpc/snapshot/fixes/source/fpc.zip
   Revision: 25838
   Last Changed Rev: 25765

2. unpacked to z:\fpc

3. download
   ftp://ftp.freepascal.org/pub/fpc/contrib/libgdb/v6.1.1/go32v2-v601.zip

   *unpacked files in directory libgdb copied to Z:\fpc\libgdb\go32v2*

3. command for compilation:

Z:\fpc>make rtl_all packages_all ide_all>x131107.log

on screen I got these mesaages:
