[Bug 1884728] Re: facing build error for qemu-4.0.0 on SUSE11 OS

[Peter Maydell]

The part of the log you quote isn't the part which caused the failure.
This bit is:

That is, we tried to link against libglib, and it failed, because the compiler 
couldn't find a working pthread library. I see from your configure options that 
you're specifying a different C compiler and also different libraries:

'--cc=/grid/avs/install/xcelium/1803/latest//tools/cdsgcc/gcc/bin/64bit/gcc'
'--extra-cflags=-I/grid/cva/p4_04/harshitm/ltssm_sj/panda/dev/src//Xtor/include'
'--extra-ldflags=-L/grid/cva/p4_04/harshitm/ltssm_sj/panda/dev/src//Xtor/lib'
'--extra-ldflags=-L/usr/lib/'
'--cxx=/usr/bin/g++'

This is what's causing your problem -- the compile has picked up a
version of libglib from whatever this /grid/ stuff is
(/grid/common/pkgs/glib/v2.56.1/lib/libglib-2.0.so) but you're trying to
get it to look for system libraries in /usr/lib when they are not
compatible with the toolchain you're using (ld complains about them
being incompatible). Trying to use this /grid/ gcc and the system g++ is
probably not going to work very well either.

I think you need to either:
 (1) drop all this /grid/ tooling and use the system compiler and libraries to 
build QEMU
 (2) don't try to use the system compiler and libraries at all, instead make 
sure you have all the libraries and tools you need in /grid/ (including the C++ 
compiler and the pthread library and the C library), and don't tell configure 
to add the system libraries to the search path

Title:
  facing build error for qemu-4.0.0 on SUSE11 OS

Status in QEMU:
  New

Bug description:
  I am trying to compile qemu-4.0.0 on suse11 OS and facing the following error 
on the console:
  ERROR: sizeof(size_t) doesn't match GLIB_SIZEOF_SIZE_T.
         You probably need to set PKG_CONFIG_LIBDIR
         to point to the right pkg-config files for your
         build target

  Looking into the config.log file following is the error that is
  listed:

  config-temp/qemu-conf.c:12:11: error: 'WACS_DEGREE' undeclared (first use in 
this function)
     add_wch(WACS_DEGREE);
             ^
  config-temp/qemu-conf.c:12:11: note: each undeclared identifier is reported 
only once for each function it appears in

  ld: skipping incompatible /usr/lib//libc.so when searching for -lc

  collect2: error: ld returned 1 exit status

  Following are the details of the tools versions:
  OS version = SUSE Linux Enterprise Server 11 (x86_64)
  python = v2.7.10
  glib = v2.56.1
  gcc = v4.8.3
  sdl2 = v2.0.12

  Can someone help me understand the cause of this error?

  regards,
  Harshit
