 Posted: Thu Mar 04, 2004 2:04 pm Post subject: can't emerge gcc with multilib |
 |
|
I have an old application that I want to be able to compile, and I'm pretty sure I need to compile it in 32-bit mode. After reading Brad's documentation on 32-bit compatiblity (http://www.gentoo.org/proj/en/base/amd64/index.xml?part=2&chap=4), I thought I knew what to do.
As I understand Brad's instructions, I need to set my USE variable to include 'multilib', then reemerge gcc, and then I can compile an app for 32-bit by adding '-m32' to the CFLAGS for that app's Makefile. Well, I don't update my machine so frequently, and I was running gcc-3.3.2-r2. I added 'multilib' to my USE variable (in /etc/make.conf) and then tried to emerge the latest stable gcc (3.3.3). This failed with some nondescript error. I then tried to reemerge 3.3.2-r2; it failed with a simliar nondescript error:
| Code: | checking for dlfcn.h... (cached) yes
checking for backtrace... yes
checking for dladdr in -ldl... yes
checking for /proc/self/exe... configure: error: Cannot check for file existence when cross compiling
make[1]: *** [configure-target-libjava] Error 1
make[1]: Leaving directory `/var/tmp/portage/gcc-3.3.2-r2/work/build'
make: *** [bootstrap-lean] Error 2
!!! ERROR: sys-devel/gcc-3.3.2-r2 failed.
!!! Function src_compile, Line 357, Exitcode 2
!!! (no error message) |
Does anybody recognize what I am doing wrong here? I'm eager to build some 32-bit apps.
Thanks in advance. |

try to upgrade to 3.3.3 first (without multilib) and recompile gcc 3.3.3 again with multilib enabled

Nope. Didn't work.
Removed 'multilib'. Upgraded to 3.3.3.
Added back 'multilib'. Tried to reemerge 3.3.3. Failed again with same error as reported above.
any other suggestions? |

| Check if you have java in your USE-flags and if you do remove it. That solved the problem for me. |

thanks frank0,
adding -java to USE appears to have made gcc compile properly. |
