Hi;
We're trying to integrate bcc as a package in buildroot with the configuration
shown below:
- Target board : Raspberry PI 3.
- Toolchain : Arm ARM 2018.11
- LLVM 7.0.1
However, buildroot includes only "LuaJIT 2.0.5"(which does not support ARM64).
So we have decided to use ARM32, which seems like bcc does not have a support
for.
The build system returned the following errors :
buildroot/output/build/bcc-v0.8.0/tests/cc/test_usdt_args.cc:65:14: error:
‘parser’ was not declared in this scope
REQUIRE(!parser.parse(&arg));
^~~~~~
buildroot/output/build/bcc-v0.8.0/tests/cc/test_usdt_args.cc:65:14: note:
suggested alternative: ‘pause’
buildroot/output/build/bcc-v0.8.0/tests/cc/test_usdt_args.cc:65:14: error:
‘parser’ was not declared in this scope
REQUIRE(!parser.parse(&arg));
^~~~~~
buildroot/output/build/bcc-v0.8.0/tests/cc/test_usdt_args.cc:65:14: note:

REQUIRE(parser.done());
^~~~~~

REQUIRE(parser.done());
Taking a close look to the file "test_usdt_args.cc" shows support for few
architectures (which does not include ARM32):
#ifdef __aarch64__
USDT::ArgumentParser_aarch64 parser("4@[x32,200]");
#elif __powerpc64__
USDT::ArgumentParser_powerpc64 parser("4@-12(42)");
#elif defined(__x86_64__)
USDT::ArgumentParser_x64 parser("4@i%ra+1r");
#endif
USDT::Argument arg;
REQUIRE(!parser.parse(&arg));
int i;
for (i = 0; i < 10 && !parser.done(); ++i) {
parser.parse(&arg);
}
// Make sure we reach termination
REQUIRE(i < 10);
}
SECTION("argument examples from the Python implementation") {
I'm wondering if there is a list of exhaustive supported architectures in bcc
and if there is any current works which aim to include support for ARM32?
