Hi All,
I'm trying to run buildman in Ubuntu 18.04 and I met the following build issue in most of the archs:
+/home/breno/.buildman-toolchains/gcc-7.3.0-nolibc/powerpc-linux/bin/../libexec/gcc/powerpc-linux/7.3.0/cc1: error while loading shared libraries: libmpfr.so.4: cannot open shared object file: No such file or directory +make[2]: *** [u-boot.cfg] Error 1 +make[1]: *** No rule to make target 'include/config/auto.conf', needed by 'include/config/uboot.release'. Stop. +make: *** [sub-make] Error 2
According to link [1] libmpfr4 has been dropped in Ubuntu 18.04 It was replaced by the package libmpfr6, seems that the toolchains being used by buildman requires libmpfr4 package.
Has anyone seen similar issue?
I could solve this issue after following link [2] and creating a symbolical link for libmpfr.so.4 as below:
$ sudo ln -s /usr/lib/x86_64-linux-gnu/libmpfr.so.6 /usr/lib/x86_64-linux-gnu/libmpfr.so.4
Just wondering if someone found a better workaround for this issue :)
A better workaround for this is to grab the libmpfr4 deb from Ubuntu 16.04 and install that. I suppose we might need to investigate moving to the Bootlin created toolchains, even if we can't also move to a newer toolchain version at the same time (for various reasons documented in other threads, we need gcc 8.3 or 9.x for all architectures to be happy).
