How to compile tbox as shared library?

[silvioprog]

Hello masters,

Looking at Build page, it seems there is no any option to compile tbox as shared library, so I changed set_kind("static") to set_kind("shared") in all .lua build files, however, when I try to compile it with my changes, it is stopped with the following error:

...
[49%]: compiling.release src/tbox/platform/arch/context.S
[50%]: linking.release libtbox.so
error: /usr/bin/ld: pkg/polarssl.pkg/lib/linux/x86_64/libpolarssl.a(ctr_drbg.o): relocation R_X86_64_32 against `.rodata.str1.1' can not be used when making a shared object; recompile with -fPIC
pkg/polarssl.pkg/lib/linux/x86_64/libpolarssl.a: error adding symbols: Bad value
collect2: error: ld returned 1 exit status

I tried to add -fPIC via add_cxflags("-fPIC"), but got same error.

So, how to compile tbox using official mechanisms?

Thank you!

Although xmake can build shared library, but tbox does not support now. Because tbox has too many interfaces.

Hm... Anyway I'm going to try to use tbox as static library. (I'm very newbie in jni + c)
Thank you!
