compilation of Code::Blocks with gcc-4.7.0 (on Linux) fails...
« on: April 16, 2012, 05:25:32 am »
Hi to all,

I have been trying to get to compile CB for some time with new gcc-4.7.0 but so far without success.

New gcc used to find some problems with sources, many of which can be allayed by using -fpermissive flag.

There is still one in ( as of version 7934) help_plugin/def.h file, where I had to use "this->find" instead existing default name scope for "find(k)".

After that it compiles fine right until final link ( even libraries are reported as installled), where it fails with a bunch of missing symbols of some (as it appears) weak references.

It seems to fail with or without -flto and with or without -fuse-linker-plugin. Also, -O2/O3 doesn't seem to matter.

I have 64-bit Gentoo Linux with latest 3.2.x kernel on Phenom II X4 955BE with 8GiB of RAM and Radeon HD6850...

Here is how I configure & compile it:

content of my_all execteable script in root source dir:

Quote
#! /bin/bash
export CFLAGS="-march=native -O2 -fpermissive -flto -fuse-linker-plugin -pipe"
export CXXFLAGS="-march=native -O2 -fpermissive -flto -fuse-linker-plugin -pipe"
make uninstall
make distclean
make clean
./bootstrap
./configure  --prefix=/usr --with-contrib-plugins=all,-BrowseTracker --with-x
make
make install

And here is tail of error log:

Has anyone tried this ? It seems it would be benefitial speedwise, since CB is complex and -flto enables optimisations across compilation modules and it seems to work with gcc-4.7.0 better than with any prior version...

Before we discuss about rarley supported compiler let me ask the obvious: You did compile wxWidgets 2.8.x with this version of GCC to?

Errm, it doesn't seem to be...  ::)

Ooops. Sorry. I've recompiled verything ( 1000+ packages) with gcc-4.7.0 adn some small part failed to build with default CFLAGS/CXXFLAGS.

I've managed to either patch them or tweak flags per package so that they compile.

But rare few had to be compiled with "old" gcc-4.6.3.

I have two versions of wxGTK:

-wxGTK-2.8.12.1 ( latest one in slot:2.8 on Gentoo)
-wxGTK-2.9.3.1  ( latest one in slot:2.9 on Gentoo)

I had discovered that first one( v2.8.12.1) was compiled with gcc-4.6.3 and without "-flto" flag, while v2.9.3.1 was compiled on gcc-4.7.0 with system default C/CXX-FLAGS="-march=native -O3 -flto -fpermissive -pipe" flags

I tr4ied just now to recompile wxGTK-2.8.12.1 with sysdefault flags on gcc-4.7.0 and failed ( no linking problems, it complains about not being able to find thread.h, I'll look into that). I repeated the attempt without "-flto" and succeeded.

I didn't try to recompile CB with such wxGTK, since having the essential library compiled without "-flto" linked into complex program misses the point of using the new gcc, so I'll try to fix wxGTK-2.8.12.1 first and then report here...  ;D

O.K. I have now managed to recompile wxGTK-2.8.12.1 with gcc-4.7.0 ( CFLAGS=CXXFLAGS="-march=native -O3 -flto -fpermissive -pipe").

Results is still the same. If I try to compile CB with -flto on gcc-4.7.0, compile fails with aforementioned error.

But when I remove -flto OR use gcc-4.6.3, it compiles fine...

It seems the lto linker bug.
You should report to gcc bugzilla or binutils bugzilla.

Or you can try to add the linker option :  -flto-partition=none

The bug is very similar with this I reported ago : http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49844

Great! I'm recompiling it now. WRT to filing a bug to that crowd, well, you can see how your bug went through- it seems it was basically ignored.

GCC crowd wants from bug filer to do his part - to analyze bug behaviour and provide simple test case.
They can't be bothered to go for lengthy C::B compilation and dig through extensive C++ code for error.

If I could do that, I would take my time and provide simple testcase, but my eyeballs hurt from all that C++pr0n of  class fornication, inheritances etcetc...

Very good if you could find a simple testcase.
I tried to reduce the source code ago, but I failed to reproduce the issue.
Only when I build a larger project, I can come across the problem ...  :(
