GnuCobol Debian Packages both Clang-LLVM , gcc

[Anonymous]

Install GnuCobol 3.1.2 build with gcc 9.3.0

Download the attached files
a) gcc_gnucobol.sh (script for installation)
b) gnucobol_3.1.2-1_amd64.deb

sudo chmod 755  gcc_gnucobol.sh
sudo .clang_gnucobol.sh /deb_file_folder/

Example:

mint@mint:~/Downloads$ sudo chmod 755 gcc_gnucobol.sh
mint@mint:~/Downloads$ sudo ./gcc_gnucobol.sh /home/mint/Downloads/

Install GnuCobol 3.1.2 build with Clang LlVM 10.0.0

Download the attached files
a) clang_gnucobol.sh
b) gnucobol_3.1.2-1_amd64_clang_10.deb

sudo chmod 755 clang_gnucobol.sh
sudo .clang_gnucobol.sh /deb_file_folder/

Example:
~~~
mint@mint:~/Downloads$ sudo chmod 755 clang_gnucobol.sh
mint@mint:~/Downloads$ sudo ./clang_gnucobol.sh /home/mint/Downloads/

That's an interesting approach.

I'm quite sure that the following works:

-echo "Install GnuCobol Depedencies"
+echo "Install GnuCOBOL runtime depedencies for the .deb package"

-sudo apt install -y libgmp-dev libncurses-dev libdb-dev libxml2-dev libjson-c-dev
+sudo apt install -y libgmp-dev libncurses libdb libxml2 libjson-c

-echo "Install GnuCobol 3.1.2 Clang 10.0.0"
+echo "Install GnuCOBOL 3.1.2 Clang 10.0.0 deb package"

I guess that for clang many packages depend on another and therefore may be removed, but I don't know.

I've tested both with a live mint 20.04 cinnamon before submitting and worked very well.

[Simon Sobisch]

I assumed so, the point was only that you likely don't need all those packages at run-time, either because they are not used when GnuCOBOL is build (like the -dev I've mentioned) or because you don't need them at all for GnuCOBOL (like clang-format) or because they are included in one of the other packages and will be auto-added by apt.

[Nikos]

I follow the instructions on the LLVM site and I don't know the packages needed for a successful build.
Maybe you can update the apt-get for the Clang-LLVM and remove those not needed.

This is an updated version off the gcc_gnucobol.sh
I have corrected the "essentials" to "essential" at line 47.

Benchmarks .

[Simon Sobisch]

For real benchmarking on a recent machine you likely want to either extend the data file to contain 200 million records or execute the code 20 times. I'd suggest:

        Procedure Division.
+        MorePerf.
+           Perform Mainline 20 TIMES. GoBack.
         Mainline.

and

-           STOP RUN

Otherwise it is just too fast to be good for comparison.
When running on GNU/Linux it is commonly better to neither use bash builtin time, nor the time binary, but perf stat -e instructions instead.

@ikonomn: Would you mind creating newer Mint packages? We currently are on 3.2-rc2 and should get the final release next week.
