[SOLVED] trouble compiling udunits-1.11.7 on Slackware64-13.37

tramni1980 · 04-21-2012, 01:31 AM

Hello,

I am running Slackware64-13.37 with kernel 2.6.38.4. I need to install the udunits-1.11.7 ftp://grads.iges.org/grads/Supplibs/...-1.11.7.tar.gz library. Yes, I do know that there is a new version, which compiles successfully on Slackware, but I actually need GrADS, and GrADS needs exactly udunits-1.11.7. Here is the compile-time error I get:

Code:

Link with -lm.

Hello,
I am not a programmer, but so long as I understand your suggestion, it says just to add the

Code:

CFLAGS='-lm'

option before running the configure script, am I right?
This made no difference.

If I have wrongly understood you, could you tell me the exact command which chooses the '-lm' linker?

Hi,

In your original message, this was the command that caused the error:

Code:

cc -o udunits -O udunits.o -L/home/marto/build/source/udunits/udunits-1.11.7/src/lib -ludunits -L/home/marto/build/source/udunits/udunits-1.11.7/src/port/misc -ludport

You should see -lm in the end of that line. You could try setting LDFLAGS before configure:

Code:

LDFLAGS='-lm' ./configure

tramni1980 · 04-21-2012, 03:38 AM

Thanks for the clarification, please apologise my ignorance.

Code:

LDFLAGS='-lm' ./configure; make

outputs the following, which I think marks no difference:

OK, I fetched the tar ball and this seemed to work: after configure,

Code:

make CFLAGS='-fPIC' LDFLAGS='-lm'

-lm links the math library into the binary. It is needed because the error message tells that it needs log10 which is not found. See man log10. And after -lm is succesfully added to the link command, the build stops at an error which tells to compile with -fPIC.

Than you very much, that did the trick!!! I also had to give the same arguments to the make install command. I wonder why
the settings do not work if they are passed only to configure, as is usually done ?
