I use a module which uses C instead of C++.
There is a feature used, which is available in C 99 but not in C++ before C++20.
It can be compiled for the target but compiling the simulator fails with the message below. I could remove the "-pedantic" once in the temporary Makefile in the build directory of the simulator (TouchGFX/generated/simulator/gcc/Makefile):
c_compiler_options_local += -pedantic $(addprefix -W,$(WARN))
Shouldn't a C file compiled with the C compiler instead of the C++ compiler? The error message says "C++ does not allow...".
if I add "-std=c99" in TouchGFX/config/gcc/app.mk to:
# Optional additional compiler flags
user_cflags := -DUSE_BPP=16 -std=c99
... then I get the following:
cc1plus.exe: error: command line option '-std=c99' is valid for C/ObjC but not for C++ [-Werror]
Again, why g++ is used instead of gcc for C files?
c_compiler := g++
c_compiler_options += -DSIMULATOR='' -g
cpp_compiler := g++
cpp_compiler_options += -g -DSIMULATOR='' -DENABLE_LOG

../awiemidevice/src/awiemi_conversion.c:173:1: error: ISO C++ does not allow C99 designated initializers [-Werror=pedantic]
{"
The code causing this is:
const struct ModelParam ch4QuotToPpm =
{
.modelName = MODELNAME_RATIONAL,
.a = -2.61246114389584,
...
