It works fine for me, the only difference is that I have a M1 not pro... Did you installed OpenSSL? If no your case isn't detected by V that's weird. Try installing it using brew install openssl. If yes I don't know.

[JalonSolov]

The C compiler found the openssl header, though they're from a really old release (1.0.2t, from the path). Maybe that's the only issue - need a newer version of openssl (and headers) to have that resolved.

[jminor]

I am also having trouble compiling/running any vweb examples on my M1 MacBookPro, though the symptom is different. V complains

builder error: Your V installation may be out-of-date. Try removing `thirdparty/tcc/` and running `make`

Even though I have a fresh clone & build from github. I can work around this by building v as x86_64 and setting VFLAGS="-d dynamic_boehm".

Side note: I have the latest brew install openssl per the advice in the thread above.

Ah! I think I might have found my problem. V was getting confused since my system has two copies of openssl on it. One in Homebrew's arm64 area /opt/homebrew/opt/openssl and one in Homebrew's x86_64 area /usr/local/opt/openssl'. When building, V was finding both, but preferring the wrong one. I was able to fix it by editingvlib/net/openssl/c.v` and commenting out the undesirable location here:

// Brew
//#flag darwin -I/usr/local/opt/openssl/include
//#flag darwin -L/usr/local/opt/openssl/lib
// Brew arm64
#flag darwin -I /opt/homebrew/opt/openssl/include
#flag darwin -L /opt/homebrew/opt/openssl/lib

After rebuilding V (now native arm64) now vweb seems to work fine.

[jminor]

It seems that both the OP and my issue were related to finding the right openssl version & architecture.

[medvednikov]

openssl is going to be embedded soon in 0.4, so this will be fixed on its own

[jminor]

Glad to hear it :)

[medvednikov]

ssl is now embedded, should work fine
