[Bug]: Gnucobol from Termux Packages cobc binary doesn't call clang properly

[vyuh]

Problem description

I was trying to compile a sample COBOL hello world program but got an error clang-14: error: no such file or directory: 'z'. Please see the following transcript showing commands and output.

$ cat helo.cob
      * Sample COBOL program
       IDENTIFICATION DIVISION.
       PROGRAM-ID. hello.
       PROCEDURE DIVISION.
       DISPLAY "Hello, world!".
       STOP RUN.

I then built Gnucobol 3.1.2 release sources in Termux environment using ./configure --prefix=$HOME/PREFIX && make && make install. I could compile the same source file helo.cob with the cobc binary of this build. The resulting binary helo worked (though it needed some help with LD_LIBRARY_PATH). I'm including terminal transcript for comparison.

Notice that the Termux packages version of cobc adds -fstack-protector-strong z to the arguments of clang. This doesn't happen with cobc binary built by me from source.

I'm hoping this can be fixed by changing something in the Termux build scripts.

What steps will reproduce the bug?

compile helo.cob with command cobc -x helo.cob. command fails with error message: clang-14: error: no such file or directory: 'z'.

Contents of helo.cob:

      * Sample COBOL program
       IDENTIFICATION DIVISION.
       PROGRAM-ID. hello.
       PROCEDURE DIVISION.
       DISPLAY "Hello, world!".
       STOP RUN.

What is the expected behavior?

Should produce executable helo from helo.cob

Please try gnucobol 3.2.1-1 when it is available shortly. Termux passes -Oz as optimisation level, but it was not recognised by gnucobol's configure script, which tries to remove optimisation levels through various sed patterns

[Grimler91]

Also note that your locally compiled gnucobol doesn't set RPATH, requiring you to use LD_LIBRARY_PATH. With termux's gnucobol that shouldn't be needed (not to make the program find libcob.so at least)

[vyuh]

I checked and found that this works as expected. Thank You for your work on Termux @Grimler91.
