linking with static library created using lf95

[Intel_C_Intel]

Hello,

I have a driver program that I would like to compile and link with a static library that has been created using lahey (lf95) compiler.

However I get unresolved external symbol reference error. kindly help


Here are the outputs of the two compilers -

With LF95:

after searching through forum, i added following code to the driver.f90


!DEC$ATTRIBUTES REFERENCE,ALIAS:"_parameters_" :: parameters
!DEC$ATTRIBUTES REFERENCE,ALIAS:"_liquidactivitycoefficients_" :: liquidactivitycoefficients
!DEC$ATTRIBUTES REFERENCE,ALIAS:"_soliddissociationequilibriumconstants_" :: soliddissociationequilibriumconstants
!DEC$ATTRIBUTES REFERENCE,ALIAS:"_liquidreactionequilibriumconstants_" :: liquidreactionequilibriumconstants
!DEC$ATTRIBUTES REFERENCE,ALIAS:"_liquiddensity_" :: liquiddensity

this gave following link error

pl. reply,
Best regards, Ranjeet.

In general, you cannot mix object code created by 2 different compilers, especially not same-language compilers. Every compiler inserts references to its own run-time library routines (g_derf, jwe_iocf in the case of LF95) and, when linked all together, they might easily clash with the other compiler's RTL calls.

a) Since you possess both compilers, why not simply rebuild the static library sources with ifort and link them to ifort driver code?
b) If that's not feasible for some reason, a better alternative would be to create a DLL using LF95 and call that from Ifort code -- DLLs isolate the dependencies much better than static libraries
c) If that's not feasible for some reason either, you might try to supply LF95's run-time libraries (whatever they're called) to the linker's command line. Like I said above, it might work and will probably get linked, but it's highly likely that you will get some strange run-time behavior.
