Bug 23165 – wipe build fails due to undefined errno

• Status: RESOLVED FIXED
• Product: Gentoo Linux

[Description Peter Gantner (a.k.a. nephros) 2003-06-20 06:15:03 UTC]

emerge wipe gives the following error. IIRC the thing with errno is related to newer glibcs (?), 
but I don't know C so I can't investigate further.

gcc -pipe -O3  -ffast-math -fomit-frame-pointer  -I. -DLINUX  -o mt.o -c mt.c
gcc  `find . -name '*.o'` -o wipe
./rand.o(.text+0xfe): In function `rand_init':
: undefined reference to `errno'
collect2: ld returned 1 exit status
distcc[4962] ERROR: compile on localhost failed with exit code 1
make: *** [wipe] Error 1

!!! ERROR: app-misc/wipe-2.1.0 failed.
!!! Function src_compile, Line 15, Exitcode 2
!!! compile problem



Reproducible: Always
Steps to Reproduce:
1. emerge wipe

Fixed in CVS.

Thanks for the patch Nicolas.
