===============
A script to check that the (Linux) executables produced by gitian only contain
allowed gcc, glibc and libstdc++ version symbols. This makes sure they are
still compatible with the minimum supported Linux distribution versions.
A script to check that the executables produced by gitian only contain
certain symbols and are only linked against allowed libraries.
For Linux this means checking for allowed gcc, glibc and libstdc++ version symbols.
This makes sure they are still compatible with the minimum supported distribution versions.
For macOS we check that the executables are only linked against libraries we allow.
Example usage after a gitian build:
find ../gitian-builder/build -type f -executable | xargs python3 contrib/devtools/symbol-check.py
If only supported symbols are used the return value will be 0 and the output will be empty.
If no errors occur the return value will be 0 and the output will be empty.
If there are 'unsupported' symbols, the return value will be 1 a list like this will be printed:
If there are any errors the return value will be 1 and output like this will be printed:
.../64/test_bitcoin: symbol memcpy from unsupported version GLIBC_2.14
.../64/test_bitcoin: symbol __fdelt_chk from unsupported version GLIBC_2.15
