runtime_loader cannot find libstdc++

[haiqu]

Recently built Lazarus from sources on a hybrid system with the GCC4 compiler. Qt runs fine, FPC runs fine, Lazarus compiles without error. When invoked, Lazarus causes the following system message:

runtime_loader cannot find libstdc++.so.6 - no such file or directory.

Bizarre.

This error is usually caused by linking together apps/libs using both the gcc2 and gcc4 runtime. In this case, you probably used a gcc4 Qt with a gcc2 fpc?

Probably the same thing happens in #11187.

OK, I got to the bottom of this one. Using 'strace -l lazarus > strace.txt' and reading the result it's clear that the system is never searching /boot/system/lib/x86 for the required libraries. You can also see this by doing 'setarch x86' then dumping the environment to screen. The library path is always the gcc2 files.

[haiqu]

And as proof, I did this:

export LIBRARY_PATH=/boot/system/lib/x86:$LIBRARY_PATH

and it started right up!

[haiqu]

NB This is a purely x86 GCC4 build, fyi.

Can you paste the result of these commands:

objdump -s --section .comment /path/to/binary

objdump -x /path/to/binary | fgrep RPATH

[haiqu]

Sure.

./lazarus: file format elf32-i386

Contents of section .comment:

0000 00474343 3a202847 4e552920 322e3935 .GCC: (GNU) 2.95 0010 2e332d68 61696b75 2d323031 345f3037 .3-haiku-2014_07 0020 5f323600 _26.

I'll attach the fgrep, it's pretty big.

[haiqu]

fgrep as requested

[haiqu]

Dunno where that .comment section got gcc2 from, although I did use a pre-packaged version of FPC and it may have been compiled with gcc2

[waddlesplash]

You must have linked with LD from GCC2 binutils, that will use the init_term_dyn and GCC2 crtbegin/crtend. Either way, this isn't a runtime_loader bug, for certain.
