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

2. unpacked to z:\fpc

*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

What I am doing wrong?

Hi Lubomir,

I think that your problem comes from the fact that you are using release go32v2 compiler version 2.6.2
to compile 2.6.3 snapshot IDE.
I was able to reproduce this problem.
The error comes from the fact that there are several variations of the environ pchar array ...
The assembler symbol can be _environ or __environ
and there is an incompatibility between 2.6.3 rtl and 2.6.2 compiler that generates a laoding of crt1.o object from libgdb.a library. This should not happen, and of course, when it does, leads to multiply defined symbols and the error you got.

You should first compiler the snapshot 2.6.3 compiler, and use this freshly generated snapshot compiler to recompile rtl packages and finally compile the IDE with libgdb.

Could you test if this works for you also?

Pierre Muller.

Hi,

Alright, this is my fault then - I wasn't aware of this change in 2.6.3 RTL for GO32v2 and hoped to simplify things for the original poster by not requiring him to go through the full building cycle. If this is necessary, using the fpcbuild.zip instead of just fpc.zip (while still unpacking the downloaded libgdb into fpcsrc/libgdb/go32v2) and running "make go32v2zip" (with the respective additional parameters, i.e. "OPT=-gl -O- -Xs-" to get executable providing the backtrace source line information in case of crash) is probably an easier option than first installing the snapshot compiler and then ensuring that this one is used rather than the last release... Anyway, sorry. :-(

Hi Pierre and Tomas,

thank you for your help but I am totally confused and do not know how to compile the compiler from snapshot.

Could you help me, please? Thank you.

I downloaded fpcbuild.zip, unpacked to Z:\fpcbuild and I got these errors:

Hi Lubomir,

No idea. :-( The line should state 'z:/pp/bin/go32v2/make.exe -C z:/fpcbuild/fpcsrc/rtl clean'. I really don't understand why it misses the directory name. Does the same happen if you call 'make rtlclean' within directory fpcsrc\compiler? Anyway, the only way for finding out what's happening is calling make with additional parameters for makefile debugging - '--debug=all -p -w --warn-undefined-variables'. If the error happens also with 'make rtlclean', use those parameters for that call (between 'make' and 'rtlclean'), otherwise they need to be added to the 'make go32v2zip' call. Note that stderr should be redirected to the same file as stdout. Make sure to zip the output before sending it (especially if you intend to send it to the list - uploading it somewhere and sending just a URL might be a better option), otherwise your post might be held for approval if your attachment exceeds limit set for this list.

Hope this helps

Tomas

Oh my god, I made a big mistake.

I'm very sorry, but you know - nobody is perfect.

I forgot to change the compiler from old one to 2.6.2, so in z:\pp was the old one :-(

Well from start:

OS = Windows Server 2003 Enterprise, 3 GB RAM, on disk z: over 1 TB free space

FPC 2.6.2 is installed in z:\pp

1. unpack fpcbuild.zip (build from 8.11.2013) to z:\fpcbuild

2. libgdb copied to Z:\fpcbuild\fpcsrc\libgdb

3. in CMD:

It seems that compilation doesn't work under Windows Server 2003 Enterprise.

I did the same under Windows XP SP3 using

make go32v2zip "OPT=-gl -O- -Xs-"

and it works up to compilation of IDE fp.pas - see attached listing fpc263.rar.

I got the same error for crt1.c even I think the compiler is compiled and used (at least as I see in LOG file):

Z:\fpcbuild>Z:\fpcbuild\fpcsrc\compiler\ppc386.exe -? Free Pascal Compiler version 2.6.3 [2013/11/11] for i386 ...
