Description Benjamin Schindler 2007-11-10 12:10:44 UTC 
I wanted to enable the old glibc libraries, because matlab does not like newer glibc. In order to make matlab (symbolic toolbox) work, I need a LD_ASSUME_KERNEL=2.4.1.

When installing glibc-2.6.1 with compat useflag enabled, I am not getting any compat-libraries besides libnss-compat. However, I need libdl, libc etc which are compatible with LD_ASSUME_KERNEL=2.4.1. When starting matlab with LD_ASS... set I get an error 
that libdl is not found

I grepped the ebuild for 2.6.1 and noted, that the if statement present in the 2.6 ebuild is gone in 2.6.1... has support been removed? 

io lib # eu-readelf -n /lib/libdl.so.2

Note segment of 32 bytes at offset 0x154:
  Owner          Data size  Type
  GNU                   16  VERSION
    OS: Linux, ABI: 2.6.9

This clearly is not compatible with LD_ASSUME_KERNEL=2.4.1 :)


Reproducible: Always
