bug#32217: Incorrect string check for PGI compilers in libtool.m4

[Anh Huynh]

Hello,

 

Since 17.1, PGI compilers have changed their -V message to print out

 

PGI Compilers and Tools

But while determining PIC flag for PGI compilers, m4/libtool.m4 file looks for “*Portland\ Group*” as seen here in line 4784 (http://git.savannah.gnu.org/cgit/libtool.git/tree/m4/libtool.m4#n4784)

 

*Intel*\ [[CF]]*Compiler*)

                 _LT_TAGVAR(lt_prog_compiler_wl, $1)='-Wl,'

                  _LT_TAGVAR(lt_prog_compiler_pic, $1)='-fPIC'

                  _LT_TAGVAR(lt_prog_compiler_static, $1)='-static'

                  ;;

*Portland\ Group*)

                  _LT_TAGVAR(lt_prog_compiler_wl, $1)='-Wl,'

                 _LT_TAGVAR(lt_prog_compiler_pic, $1)='-fpic'

                  _LT_TAGVAR(lt_prog_compiler_static, $1)='-Bstatic'

                  ;;

 

As a result in certain situations the -fpic flag does not get set properly.

 

Let me know if you need more information.

 

Thank you.
