Public bug reported:
From the ubuntu24.04 docker image, trying to compile and link a
catch2-based test program results in undefined references.
Steps to reproduce:
sudo docker run --rm -it ubuntu:24.04
apt update
apt install build-essential g++ catch2
cat > test.cpp << 'EOF'
#include <catch2/catch_test_macros.hpp>
TEST_CASE("test", "[test]") {
int a = 1;
REQUIRE(a == 1);
}
EOF
c++ -lCatch2Main -lCatch2 test.cpp
Expected Results:
It should be able to compile and link and run successfully.
Actual Results:
