I get error:

Do you have any idea how to solve that?

2

When did you get this error message and what do you want to do?
What do you want to install and how do you install (zypper/ YaST)?

3

When I’m build Code::Blocks RPM package in OBS for opensuse 12.3 and higher.

4

Hm, I don’t see anything wrong there. The types are all ok.

Maybe that file misses an “#include <stdio.h>” and therefore fdopen is not declared (so the compiler would expect the return code and mode2 to be int)?
Try to patch that in.

5

???
AFAICS codeblocks builds just fine in your home repo, for 12.3, 13.1, and Factory. :\

6

not build one codebloc contrib plugins I removed it.

No stdio.h include in bzlib.c.
All build log

Yes, but there is one in bzlib_private.h which is included by bzlib.c, although only if BZ_NO_STDIO is not defined. Maybe that is somehow defined causing the problem?
Your build log confirms that stdio.h is not included: (fdopen is declared in stdio.h)

  683s] bzlib.c: In function 'bzopen_or_bzdopen':
  683s] bzlib.c:1431:7: warning: implicit declaration of function 'fdopen' -Wimplicit-function-declaration]
  683s]        fp = fdopen(fd,mode2);
  683s]        ^
  683s] bzlib.c:1431:10: warning: assignment makes pointer from integer without a cast [enabled by default]
  683s]        fp = fdopen(fd,mode2);
  683s]           ^

So maybe try to patch out that “#ifndef BZ_NO_STDIO” in line 27 of bzlib_private.h, or patch in “#include <stdio.h>” in bzlib.c, or find out why BZ_NO_STDIO is defined and change that (maybe some configure switch?).

The only thing about BZ2 I can find in your build log (or in the configure script) is this:

  153s] checking for library containing BZ2_bzopen... no

So maybe it would suffice to add “BuildRequires: libbz2-devel” ?

Thanks. rotfl!

Confirmed, adding “BuildRequires: libbz2-devel” fixes the build! :slight_smile:
