Re: [platform-testers] Request for testing GnuCOBOL 3.1-rc1

[Paul Zimmermann]

       Dear Simon,

I tested GnuCOBOL 3.1-rc1 on my x86_64 laptop (Intel core i5, gcc 5.4.0,
Ubuntu 16.04.6 LTS).

The first remark is that you say that berkeley-db is optional, but this does
not seem the case for configure:

zimmerma@mure:/tmp/gnucobol-3.1-rc1$ ./configure
...
configure: error: Berkeley DB db.h is missing

Then with ./configure --with-db=no it works fine, and I get:

zimmerma@mure:/tmp/gnucobol-3.1-rc1$ make check
...
1015 tests behaved as expected.
34 tests were skipped.

I also tried on gcc135 (https://gcc.gnu.org/wiki/CompileFarm) where I get
more interesting results:

[zimmerma@gcc135 gnucobol-3.1-rc1]$ ./configure --with-db=no 
CC=/opt/at12.0/bin/gcc 
...
[zimmerma@gcc135 gnucobol-3.1-rc1]$ make -j4
...

Now on a machine with Intel compiler:

[zimmerma@sirocco11 gnucobol-3.1-rc1]$ icc -v
icc version 19.0.4.243 (gcc version 9.2.0 compatibility)

[zimmerma@sirocco11 gnucobol-3.1-rc1]$ ./configure CC=icc
...
[zimmerma@sirocco11 gnucobol-3.1-rc1]$ make
...
icc -DHAVE_CONFIG_H -I. -I..  -I..   -O2 -pipe -finline-functions -Wall -wd1419 
-vec-report0 -opt-report 0 -MT dummymac.o -MD -MP -MF .deps/dummymac.Tpo -c -o 
dummymac.o dummymac.c
...
icc: command line remark #10148: option '-vec-report0' not supported
icc: command line error: option '-opt-report 0' is not supported. Please use 
the replacement option '-qopt-report 0'

Thus removing -vec-report0 from CFLAGS, and changing -opt-report 0 into
-qopt-report 0:

[zimmerma@sirocco11 gnucobol-3.1-rc1]$ make CFLAGS="-O2 -pipe 
-finline-functions -Wall -wd1419 -qopt-report 0"
...
icc: command line remark #10010: option '-qopt-report 0' is deprecated and will 
be removed in a future release. See '-help deprecated'
...
icc: command line error: option '-opt-report 0' is not supported. Please use 
the replacement option '-qopt-report 0'

This one seems to come from COB_CFLAGS:

[zimmerma@sirocco04 gnucobol-3.1-rc1]$ make CFLAGS="-O2 -pipe 
-finline-functions -Wall -wd1419 -qopt-report 0" 
COB_CFLAGS="-I/usr/local/include -vec-report0 -qopt-report 0 -Wno-pointer-sign 
-pipe"
...

This still fails in gnucobol-3.1-rc1/extras:

icc: command line error: option '-opt-report 0' is not supported. Please use 
the replacement option '-qopt-report 0'

I gave up here.
