g++ compile is success，however emsdk compile failed

MohitS05 commented 1 year ago

These are linker errors. The APIs/Symbols being mentioned like RSA_public_encrypt and PEM_read_bio_RSA_PUBKEY have been deprecated in OpenSSL 3.0. I am not sure about BIO_new_mem_buf. You can read more about it on PEM_read_bio_RSA_PUBKEYand PEM_read_bio_RSA_PUBKEY

this is because i need to compile openssl source code on Mac first, how ever I got another stuck problem when use emmake make -j 12 build_generated libssl.a libcrypto.a, the error likes this：

Something is very wrong there. -DCMAKE_CROSSCOMPILING_EMULATOR and -DCMAKE_TOOLCHAIN_FILE are argument for cmake, and should not be passed to the compiler like that.
