MacOS X Catalina ifort linking problem

gragnani__eva — Thu, 06 Feb 2020 18:25:24 GMT

Hi,

my problem is that the linker fails with:
ld: library not found for -llibfparser.a

when I use:

ifort -L/usr/local/lib/ -I/usr/local/include/fparser-v1.1/ -llibfparser.a test.f90

if I compile specifying the complete path all is OK

ifort -I/usr/local/include/fparser-v1.1/ /usr/local/lib/libfparser.a test.f90

this gives me the correct executable file.

There are two modules that are correctly seen through the -I switch what seems to not work is the -L switch.

Thanks

(sorry for my English)

try ordering -L and -l

try ordering -L and -l together like this:

ifort -I/usr/local/include/fparser-v1.1 -L/usr/local/lib -llibfparser.a test.f90

-L sets a library path and usually immediately preceeds the -l libraries.

Let me know if this works.

The convention used by the

The convention used by the Linux linker ld for specifying library files is that the library file name is obtained by adding the prefix lib and adding the suffix .a to the ld argument prefixed by -l. Thus, -lmath is shorthand for libmath.a .

For more details of the -l command line option, see https://ftp.gnu.org/old-gnu/Manuals/ld-2.9.1/html_mono/ld.html#SEC3 .

Thanks Ron, but unfortunately

Thanks Ron, but unfortunately nothing changes, I still have ld: library not found for -llibfparser.a.

Thanks mecej4, it works!

Thanks mecej4, it works!

ifort -L/usr/local/lib/ -I/usr/local/include/fparser-v1.1/ -lfparser test.f90

Well, now from the terminal

gragnani__eva — Fri, 07 Feb 2020 01:12:02 GMT

Well, now from the terminal everything works but from xcode I continue to have the usual error.

In Targets --> Build Phases --> Link Binary With Libraries I have added libfparser.a and I also tried changing the name to fparser but the problem remains.

Obviously I set the directory for the .mod file and for the library:

Build Settings --> Search Paths --> Header Search Paths --> /usr/local/include/function_parser/

Build Settings --> Search Paths --> Library Search Paths --> /usr/local/lib/

Ideas?

Thanks Eva

I do not have a Macintosh and cannot help you with Xcode. I do not understand what you mean by "the usual error".

Do note that Xcode is deprecated with the current compiler release, and will be unsupported in a future release, according to https://software.intel.com/en-us/forums/intel-fortran-compiler/topic/844666 .

"the usual error" is:

"the usual error" is:

ld: library not found for -llibfparser.a

Another question, if Xcode is deprecated what IDE is available for MacOS? Eclipse, Visual Studio Code ...

Thanks Eva

In the place where you entered "libfparser.a" in Xcode, enter "fparser".

Whatever is available for MacOS. Someone else who is a Macintosh user will have to help you on that.

Thanks for the reply macej4,

gragnani__eva — Sun, 09 Feb 2020 22:07:31 GMT

Thanks for the reply macej4, but the problem is that xcode has a dialog box for loading a file (that is the library) and doesn't allow you to specify a name.
