I have the same problem, even with 1.10.0-r2.
``` -- Found OpenSSL: /usr/lib64/libcrypto.so (found suitable version "3.3.2", minimum required is "1.1.1") -- Found Libbrotlienc: /usr/lib64/libbrotlienc.so (found suitable version "1.1.0", minimum required is "1.0.9") -- Found Libbrotlidec: /usr/lib64/libbrotlidec.so (found suitable version "1.1.0", minimum required is "1.0.9") -- Looking for SSL_provide_quic_data -- Looking for SSL_provide_quic_data - not found CMake Error at CMakeLists.txt:156 (message): Unable to build OpenSSL backend due to lack of QUIC support in /usr/lib64/libssl.so;/usr/lib64/libcrypto.so ``` Please share `emerge -pvO dev-libs/openssl` output and also try with boring flags (CFLAGS="-O2" CXXFLAGS="-O2" LDFLAGS="-Wl,-O1" and no bashrc stuff enabled). It's possible some flag is confusing the configure check.
``` [ebuild R ] dev-libs/openssl-3.3.2-r2:0/3::gentoo USE="asm quic -fips -ktls -rfc3779 -sctp -static-libs -test -tls-compression -vanilla -verify-sig -weak-ssl-ciphers" ABI_X86="(64) -32 (-x32)" CPU_FLAGS_X86="(sse2)" 0 KiB ``` The same error with "boring flags" and no bashrc.
I did a little bit of an investigation. It seems that ngtcp2 really doesn't work with OpenSSL. It expects a patched version of openssl (github.com/quictls/openssl). OpenSSL's own implementation of QUIC is useless for ngtcp2.
