Error compiling a program with boost libraries -> strerror_r

iteam · 06-28-2011, 04:56 AM

Hi all,

I'm compiling a project that uses boost libraries (1.45.0) for a MIPS target, and when trying to compile with bjam I get the following error:

Code:

libboost_system-mt.a(error_code.o): In function `(anonymous namespace)::generic_error_category::message(int) const':
error_code.cpp:(.text+0x55c): undefined reference to `__glibc_strerror_r'
collect2: ld returned 1 exit status

Does it mean that the compiler doesn't find the library? Or what does it mean? I'm trying to solve the problem but actually I don't know what is the problem.

Please, could someone help me?

"undefined reference" usually means you are missing a library, yep.
afaik: __glibc_strerror_r is in uClibc ... make sure you have it and that it is in your path.

I need to compile my program using glibc because it needs one feature that it is not available on uClibc. Can I compile with the two libraries?

I found this in a forum, it seems that my glibc (2.6.1) do have strerror_r:

checking if strerror_r is on glibc version >= 2.0... yes

and I think that the library is present because before the error many objects compile correctly.

I finally solve the problem adding an option that recompiles all the sources, but now I can't run the program compiled with glibc in my OpenWRT firmware, I suppose because it uses uClibc.

I run the file command for my program and the result is:

Code:

ELF 32-bit MSB executable, MIPS, MIPS32 rel 2 version 1, dynamically linked (uses shared libs), for GNU/Linux 2.4.0, with unknown capability 0x41000000=0xf676e75, not stripped

Some questions:
Why it is compiled for GNU/Linux 2.4.0, this is not my version, where I choose that parameter?
I read it is possible to run a program compiled with glibc in OpenWrt with uClibc if you compile statically, adding --static to CFLAGS, why doesn't work that?
