5 years ago None whatsoever. The project looks abandoned.

5 years ago libbfd which is used by this project is pretty volatile. it's part of binutils and afaict there's no stable ABI (so imo it's been a pretty bad choice to use it for this project). anyway, the issues you're experiencing may be related to that your libbfd is a static lib (libbfd.a), not a dynamic lib, so dependencies aren't pulled in automatically. most of the symbols i see missing seem to be from libiberty, which is another GNU library (used by gcc and binutils) not really meant to be used by external projects. maybe adding -liberty -lz -ldl -lc to the command line could fix it, but i would look into getting a dynamic build of libbfd.

5 years ago I was creating a rpm package. Things to link to system libraries when possible, fix installation paths, compilation flags and a few other minor details.

5 years ago Hi Luigino and rofl0r, As noted by rofl0r, the symbols that trigger an error, such as "objalloc_free_block" are not called from wcc. The linking problem would come from a problem when building libbfd/libopcode. I am glad to hear you managed to solve the matter by linking against a version of libbfd that is a shared library instead of a static library. I was about to suggest you built against this version: ftp://sourceware.org/pub/binutils/snapshots/binutils-2.31.90.tar.xz using the following steps: wget -c ftp://sourceware.org/pub/binutils/snapshots/binutils-2.31.90.tar.xz tar -xvJf binutils-2.31.90.tar.xz mkdir build -p cd build ../binutils-2.31.90/configure --with-sysroot=/ --enable-shared --enable-targets=all --build=x86_64-linux-gnu --host=x86_64-linux-gnu --enable-plugins --prefix=/usr --enable-ld=default --enable-gold --enable-multilib build_alias=x86_64-linux-gnu host_alias=x86_64-linux-gnu make -j8 make install
I'm glad you could solve it by yourself \o/

5 years ago Linking problem solved. For future reference, the following steps to build binutils, libbfd and libopcode are known to work :
wget -c ftp://sourceware.org/pub/binutils/snapshots/binutils-2.31.90.tar.xz tar -xvJf binutils-2.31.90.tar.xz rm -rf ./build/ mkdir build -p cd build ../binutils-2.31.90/configure --with-sysroot=/ --enable-shared --enable-targets=all --build=x86_64-linux-gnu --host=x86_64-linux-gnu --enable-plugins --prefix=/usr --enable-ld=default --enable-gold --enable-multilib build_alias=x86_64-linux-gnu host_alias=x86_64-linux-gnu make -j8 make install
Using openSUSE Tumbleweed, this happens:
Adding a -lz produces this:
And then I'm stuck.
Any hints?
