hello @yorknb962 ! libBLS only supports gcc-9. you can either use gcc-9 instead of gcc-7 or try to manually edit cmake file to make it compatible with gcc-7

[yorknb962]

Thank you for your reply!

Inspired by your reply, I changed my symbolic link to gcc-9 and g++-9.
Now I can compiler this project successfully!

However, when i run "./build/bls_unit_test -t libBLS/" and "./build/bls_unit_test --list_content ", it still have problem as follow:

"Bash: syntax error near unexpected symbol 'newline'";
and "libBls*
zeroSecretKey*
singleBlsrun*
SimillarHashes*
BlsThresholdSignatures*
BlsThresholdSignaturesFalse*
BlsThresholdSignaturesReal*
simillarSignatures*
Exceptions*
SignVerification*"

[olehnikolaiev]

please try ./build/bls_unit_test -t libBls/

[yorknb962]

Thanks you so much.
