mldonkey on gentoo (not compiling)

emerging mldonkey

dies on package 'lablgtk-1.2.5'

gcc 3.3.4 20040623 (Gentoo Linux 3.3.4-r1)

you can try with:

export LD_ASSUME_KERNEL=2.3.98

and then emerging mldonkey.

what will that do?

[CoffeeMan]

emerge --inject dev-ml/lablgtk-1.2.5 this will hide the conflicting package from portage. Then emerge mldonkey.

The problem is located in the nvidia tls nvidia library that doesn't support the new tls implementation (glibc 2.3)
a little explanation of the LD_ASSUME_KERNEL

the LD_ASSUME_KERNEL is an environment variable (is not hardcoded) used by ld,
every shared library can tell the ld in glibc which minimum OS ABI (Application Binary Interface) version is needed.
The information about the minimum OS ABI version is encoded in a ELF (you can see it with 'readelf -an ./test |grep -i abi')


from the NVIDIA README guidelines driver:

Q: I want to use Valgrind with OpenGL applications, but my
distribution uses ELF TLS, and Valgrind cannot yet deal with NVIDIA's
ELF TLS OpenGL.

A: You can set the environment variable LD_ASSUME_KERNEL to something
below "2.3.99" (for example: `export LD_ASSUME_KERNEL 2.3.98`).

NVIDIA's OpenGL libraries contain an OS ABI ELF note that indicates
the minimum kernel version that is required to use the library.

The ELF TLS OpenGL libraries have an OS ABI of 2.3.99 (the first
Linux kernel that contained the necessary LDT support for ELF TLS),
while the non ELF TLS OpenGL libraries contain an OS ABI of 2.2.5.

The run-time loader will not load libraries with an OS ABI greater
than the current kernel version. The LD_ASSUME_KERNEL environment
variable can be used to override the kernel version that the run-time
loader uses in this test.

By setting LD_ASSUME_KERNEL to any kernel version below 2.3.99,
you can force the loader to not use the ELF TLS OpenGL libraries,
and fall back to the regular OpenGL libraries.

If, for some reason, you need to remove this OS ABI note from the
NVIDIA OpenGL libraries, you can do so by passing the .run file the
"--no-abi-note" option during installation.

thanks markel, when i dont have to run to work, ill try it
