cannot find -l-static-libgcc when building gcc from source

cannot find -l-static-libgcc when building gcc from source

[Eric Pellegrini]

Hi all,

I try to build gcc (9.3.0) from source on ubuntu focal using the following
configure call:

./configure --enable-shared --enable-multilib --prefix=/opt/gcc

The configure runs OK but when building/linking I get the following error:

libtool: link: gcc -shared  -fPIC -DPIC  .libs/lto-plugin.o   -l
-static-libgcc -static-libstdc++ -static-libgcc
../libiberty/pic/libiberty.a   -Wl,-soname -Wl,liblto_plugin.so.0 -o
.libs/liblto_plugin.so.0.0.0
/usr/bin/ld: cannot find -l-static-libgcc

It seems that some gcc linker options have been but in the wrong
place. I have the same mistake with another version of gcc (6.5.0) so
the
problem seems to be on my side. Would you have any idea about what is
wrong with my settings ? Am I missing a dependency ?

many thanks in advance for your help

Eric

Don't do that, see https://gcc.gnu.org/wiki/InstallingGCC

There's an argument missing here, it should be -l SOMETHING

> -static-libgcc -static-libstdc++ -static-libgcc

and that means the -static-libgcc gets treated as the argument to -l

My guess is you have something defined in your environment, like
LDFLAGS=-l or something like that. Check the output of 'env' and unset
anything you don't need.

I should have trusted the manual. The solution to my problem was just to
perform the build in a directory outside the source
directory as indicated. Sorry for the inconvenience and thx for your help.
