Build error with gcc and cortex_m7/gcc/libtouchgfx-float-abi-hard.a

[MNils.2]

Hi, 
how exactly is the cortex_m7/gcc/libtouchgfx-float-abi-hard.a built (i.e compile and link options)?

For example if a make a object dump on the lib I get:
touchgfx::muldiv(long, long, long)

But the header file use int32_t instead of long and that gives a link error.
undefined reference to `touchgfx::muldiv(int, int, int)

If I change the header file to use long instead it builds.

Strange. The int32_t type usually is defined as long, not int. Do you redefine it somewhere?

I´m using Zephyr toolchain, apperently the default definition of int32_t is int in Zephyr.
However there is a config option for this that solves my problem.
CONFIG_ENFORCE_ZEPHYR_STDINT=n
