Unable to install flang from ports FreeBSD-11.2

R

runix

I am not able to compile 'flang' via ports. The log is as follows,

Bash: 
root@electron:/usr/ports/devel/flang # make install clean

Stop.

It looks like an issue with libpgmath which simply fails under FreeBSD11.2 via ports. Could someone shed some light on this.

EDIT:

I tried compiling libpgmath. However, it fails saying the following:

Code: 
root@electron:/usr/ports/math/libpgmath # make install clean
===>  libpgmath-g20180904_1 not supported on older than 12.0, no cpuid bit
support.
*** Error code 1

Stop.
make: stopped in /usr/ports/math/libpgmath

Looks like, the port version that I have, doesn't support FreeBSD 11.2. Is it true? If so, what is the alternative?

Any help would be much appreciated.
 
Thank you SirDice. I needed "flang" because I was getting the following error, when trying to pip3 install -v scipy

Code: 
    running build_clib
    customize UnixCCompiler
    C compiler: cc -Wno-unused-result -Wsign-compare -O2 -pipe -fstack-protector -fno-strict-aliasing -fPIC
    
    creating /tmp/tmp_r1rtzvl/tmp
    creating /tmp/tmp_r1rtzvl/tmp/tmp_r1rtzvl
    compile options: '-MMD -MF /tmp/tmp_r1rtzvl/file.c.d -c'
    cc: /tmp/tmp_r1rtzvl/file.c
    customize UnixCCompiler using build_clib
    building 'dfftpack' library
    error: library dfftpack has Fortran sources but no Fortran compiler found

I tried setting set CC=gcc8 but to no avail. Do I need to start a new thread?

It's not a compiler issue, it's the kernel that's missing certain functionality that prevents it from building on anything below 12.0.

You mean this for pip3 install -v scipy. I am wondering, how could that be when the error says,
Code: 
    error: library dfftpack has Fortran sources but no Fortran compiler found

Or I am mistaken your advice. Thank you for your kindness.
 
Yes did try that. But Ithought it would be nice to have things under local virtual environment than global installation. That's why I was trying to install with pip[CMD]. Ihave upgraded my system to 12.0 and going to try with [CMD]flang installed. Let me post back. Thank you.[/CMD][/CMD]

I had the same issue. I solved it by installing the default gcc meta port:
pkg install gcc or cd /usr/ports/lang/gcc/ && make install clean
