cross compilation to arm-eabi

[ManiInn]

Hi,

I am able to cross compile ws4d-gsoap source using arm-eabi present in
android toolchain.

But at the end I get linker error before creating the C executable

ld: this linker was not configured to use sysroots

Please let me know how to add the ld flags in cmake build system.

Regards,
ManiInn

I didn't have time to further look at this issue, and won't be able to
look at it until wednesday. The last time I looked at this issues I had
problems to to create a toolchain file that passes the compiler check of
cmake. So it looks like you made more progress. Could you send me your
toolchain file and how you call cmake for cross compilation.

You can use the CMAKE_SHARED_LINKER_FLAGS and CMAKE_MODULE_LINKER_FLAGS
in the toolchain file. See
http://trac.e-technik.uni-rostock.de/projects/ws4d-gsoap/browser/trunk/toolchains/x86-64-linux-gnu.cmake
for an example.

Hi Elmar,

I get the following error when i cmake with the android toolchain i
have created. I have pasted the toolchain for android after the cmake
configuration.
