Error in using pkg-config with gcc in fish

[bigpotato920]

I use fish shell on Arch Linux. I was trying to compile a c program using gtk library.But When I try to compile it using the following command in fish:

sudo gcc -shared -o libsublime_imfix.so sublime_imfix.c (pkg-config --libs --cflags gtk+-2.0) -fPIC

it shows the following errors:
gcc: error: unrecognized command line option ‘-pthread -I/usr/include/gtk-2.0 -I/usr/lib/gtk-2.0/include -I/usr/include/pango-1.0 -I/usr/include/atk-1.0 -I/usr/include/cairo -I/usr/include/pixman-1 -I/usr/include/libdrm -I/usr/include/gdk-pixbuf-2.0 -I/usr/include/libpng16 -I/usr/include/pango-1.0 -I/usr/include/glib-2.0 -I/usr/lib/glib-2.0/include -I/usr/include/freetype2 -I/usr/include/libpng16 -I/usr/include/harfbuzz -I/usr/include/freetype2 -I/usr/include/libpng16 -I/usr/include/harfbuzz -lgtk-x11-2.0 -lgdk-x11-2.0 -lpangocairo-1.0 -latk-1.0 -lcairo -lgdk_pixbuf-2.0 -lgio-2.0 -lpangoft2-1.0 -lpango-1.0 -lgobject-2.0 -lglib-2.0 -lfontconfig -lfreetype ’
but when I switch to bash and run :

sudo gcc -shared -o libsublime_imfix.so sublime_imfix.c `pkg-config --libs --cflags gtk+-2.0 `-fPIC

it works fine, could you help me with that?

See #982 - you need to add | tr ' ' '\n' or similar to the end of the pkg-config command substitution.

When I use a normal user I try:

sudo eval gcc -shared -o libsublime_imfix.so sublime_imfix.c (pkg-config --libs --cflags gtk+-2.0) -fPIC

The output is ： sudo: eval: command not found
But When I switch to root it works fine.

[zanchey]

If you want to do it that way, use eval sudo, not sudo eval.

What's mystifying to me is why the sudo eval ... works. Did you perhaps not run the command with sudo as root?

[bigpotato920]

yeah , the source code is located at /opt/xxx, so I have to have root priveledge

I think there's nothing for fish to do here. The issues with pkg-config are well known. Please comment if you think there's more to do.
