uclibc and gcc

z4ziggy · 2005-03-31 20:29:20

im trying to build an Arch uclibc based system, and i already have a root system built using the buildroot tool from uclibc. ive started making the base packages and most compiles fine, but im having problems with recompiling the gcc package under the uclibc system (error: "stage1/libgcc_s.so: undefined reference to `dl_iterate_phdr'").
ive looked in the buildroot toolchain and saw it uses several patches for gcc (3.4.3) and tried to apply them - most apply fine but some dont, and im still getting the same error. does anyone has any experience with repackaging gcc package under uclibc?

tnx.

i have tried the same with my crux system (a half year ago) and i dont get it work it seems that gcc 3.4 has many problems with uclibc , but you can try ->-> http://buildroot.uclibc.org/ <-< who knows maybe the uclibc´s guys know how to make it work....

tnx, buildroot is what i used to build the initial uclibc system - now im trying to make it the "Arch" way - ie, PKGBUILDS. i tried following LFS method and obviously it works, but since the rules dont apply to PKGBUILDs im looking for someone who made uclibc-based-packages already... i've read some posts from users having a uclibc based system, i hope some made PKGBUILDs too...

ive emailed the buildroot maintainer asking for the gcc 3.4.3 patches prerequisites, so i hope to get some info there.

I've built a uclibc based mini-Arch using the LFS bootstrap method. I ran into the dl_blahblah problem and I think the trick was to build gcc with --disable-shared. This does not create a static gcc just static libraries. Also I didn't build C++ so this may not work for you.

I currently have 47 packages, all console based cause I didn't bother with X. Unfortunately I don't have the webspace to host the packages.

Good luck.

k, tnx for that, this package gave me another error.
the author emailed be back specifying which patches should be applied but this gave same error as your package did. so that got me thinking, so i traced the problem down to missing include uclibc files under /usr/include/bits... i will email the author once i'll have my email working again :S

tnx again.

Interesting. Are you cross-compiling or native? My build works within a native uclibc system.

z4ziggy · 2005-04-03 04:56:46

native. also, please check your pm
