In GCC I typed in the terminal:
gcc -wall -o nomedoarquivo.c nomedoexecutavel
or if you only had 1 .c file [NOTE: typed "a" to facilitate the executable name]:
gcc -wall -o *.c a
The restriction I used, if there was in the code the math.h library, I had to add -lm to the code. Here it would look like this:
gcc -wall -o *.c a -lm
How should I type to compile the same file using Clang so that problems appear in the code? Do you have any restrictions?
the parameter is -Wall
I use it in a different order than the one you are using. I think in the end it becomes clearer.
clang -Wall nomedoarquivo.c -o nomedoexecutavel
clang -Wall *.c -o a
clang -Wall *.c -lm -o a
The clang is built in a very modularized way so that the command line processor (called driver ) is completely separate from the compiler itself. There are basically two drivers. One that has an identical interface to GCC and a much newer one that simulates MSVC tools.
This means that all you have to do is s/gcc/clang/g . All gcc options will work without problems. To report a healthy amount of alerts use -Wall -Wextra .
