Hi
I do:
g++ -L/usr/lib/x86_64-linux-gnu/libfreetype.a -L/usr/lib/x86_64-linux-gnu/libcurl.a -m64 -static-libgcc -DCURL_STATICLIB -I/usr/lib/x86_64-linux-gnu/libcurl.a -Wl,--version-script=exports.txt -shared -o "lin.xpl" ./BitmapSupport.o ./fontmgr.o ./image.o ./main.o ./myList.o ./rain.o ./shader.o -lGL -lGLEW
and get the runtime error:
dlerror:/home/michael/xplane/aircarft/plugin/lin.xpl: undefined symbol: curl_easy_perform
Many thanks for help
-L is not doing what you think it is. -l isn't used for linking, and also doesn't take a file.
I guess I need to compile curl myself without any dependencies.

Am I missing something? -l is most definitely used when linking: https://gcc.gnu.org/onlinedocs/gcc/Link-Options.html#Link-Options

if I add -lGL -lGLEW -lfreetype -lcurl Eclipse uses the shared libs not the static. What to do? Thanks

Have you compiled GLEW freetype and curl into static libraries first?
Yes except freetpye. With the below I get a curl runtime error and for the others are shared not static libs used.

lowecrase ell yes, the OP however uses uppercase I which his for finding include files. The font is broken here, see the image I took after copy/pasting some text to my computer.
