We need to specify a custom GCC/G++ compiler location using Gradle's cpp-library and cpp-application plugins. According to the docs tool chain section:
Linux To build on Linux, install a compatible version of GCC or Clang. The C++ plugins will discover GCC or Clang using the system PATH.
Prepending the PATH environment variable with a path to the desired g++ doesn't seem to get picked by Gradle.
How can you direct Gradle to get GCC/G++ from a custom path?
I believe you can add a custom toolchain section to the build.gradle file, something like:
toolChains {
custom_gcc_toolchain(Gcc) {
target("<target_platform>") {
path '<path_to_custom_gcc_folder>'
cCompiler.executable '<c_compiler_executable>'
assembler.executable '<assembler_executable>'
linker.executable '<linker_executable>'
}
}
}
Finally found that this worked:
model {
toolChains {
gcc(Gcc) {
path '/custom/path/to/gcc-7.1.0/bin/'
}
}
}
