Subject: compiling SPECCPU2006 against Musl
Dear mailing list,
I am curious if anyone has any insight on how to link the SPECCPU2006
benchmarks against Lusl Libc. Reading FAQ I saw that Musl does *not* have
C++ support out of the box but can still "hopefully" work in some cases
against glibstdc++
I havent found any resources or guides on-line of people doing this.
Anyways I am only focusing on the C implementation SPEC benchmarks and out
of this subset I was still only able to compile a few. The following do not
compile against MUSL:
400.perlbench
403.gcc
462.libquantum
I tried to use both clang 6.0.0 and gcc and got the following error below
(Dump at end of email). Any thoughts?
for perlbench - at first was "undefined reference to __isnan" but then
after adding -I/path/to/musl/install/include I got even more errors. I am
using the -std=gnu89 flag since this was how SPEC documented its fix for a
multiple definition error. The other 2 benchmarks show similar errors.
Sincerely,
K Jelesnianski
