[Solved] Xcode Server Build: “Multiple matching codesigning identities found”

It looks like a bug in Server did in fact introduce a duplicate signing identity. I reported it as rdar://21080937, if you’d like to dupe it. In order to fix it, I had to learn about how Xcode Server stores signing identities (thanks entirely to an extremely helpful answer to an unrelated question). Xcode Server … Read more

[Solved] Error: Cannot install in Homebrew on ARM processor in Intel default prefix (/usr/local)

For what it’s worth, before installing Homebrew you will need to install Rosetta2 emulator for the new ARM silicon (M1 chip). I just installed Rosetta2 via terminal using: /usr/sbin/softwareupdate –install-rosetta –agree-to-license This will install rosetta2 with no extra button clicks. After installing Rosetta2 above you can then use the Homebrew cmd and install Homebrew for … Read more

[Solved] How to use fflush in c on OS/X [closed]

Calling fflush(stdin); invokes undefined behavior. You should not use this to flush characters from the standard input buffer. Instead, you can read the characters upto the next linefeed and ignore them: int c; while ((c = getchar()) != EOF && c != ‘\n’) continue; You can also use scanf() for this, but it is tricky: … Read more

[Solved] Why can I have an OpenGL shader class, but not a VAO class?

The problem has nothing to do with the VAO, but with the VBO. Since you pass a pointer to the constructor: void GSMesh::build(GLfloat *arrFVertex, GSShader *shader, int _intNumVertex) { glBufferData(GL_ARRAY_BUFFER, sizeof(arrFVertex), arrFVertex, GL_STATIC_DRAW); } sizeof(arrFVertex) = sizeof(GLfloat*) which is the size of the pointer, not the size of the array pointed to. The correct code … Read more

[Solved] For more details see: ’go help gopath’

Try: mkdir -p $GOPATH/bin The error you’re seeing is the installation directory doesn’t exist, so install can’t do anything. Also, there’s a typo here: export GOPATH=”/Users/skan/Documetns/study/golang” So, same reasoning, but, try Documents solved For more details see: ’go help gopath’

[Solved] Can not flip sign

You can’t do it in a completely portable way. Rather than dealing with int64_t, let us consider int8_t. The principle is almost exactly the same, but the numbers are much easier to deal with. I8_MAX will be 127, and I8_MIN will be -128. Negating I8_MIN will give 128, and there is no way to store … Read more
