Hi Kevin:
Thank you very much for your reply!
Your are absolute right. The wsmp was written by Fortran.
After I added the underscore, I have new "undefined reference" coming up.
Here is a few examples of them:
: undefined reference to `ftn_i_jishft'
../lib/libwsmp64.a(torder.o)(.text+0x11f9): In function `fllagbgref5_':
: undefined reference to `ftn_i_jishft'
../lib/libwsmp64.a(torder.o)(.data+0x10): In function `.C4_283':
: undefined reference to `pgf90_compiled'
../lib/libwsmp64.a(kl.o)(.text+0x99): In function `fllagbkref_':
: undefined reference to `__mth_i_dlog'
../lib/libwsmp64.a(kl.o)(.text+0xbb): In function `fllagbkref_':
: undefined reference to `__mth_i_dlog'
../lib/libwsmp64.a(kl.o)(.text+0x2479): In function `fllaglastbk_':
: undefined reference to `__mth_i_dlog'
../lib/libwsmp64.a(kl.o)(.text+0x249b): In function `fllaglastbk_':
: undefined reference to `__mth_i_dlog'
../lib/libwsmp64.a(kl.o)(.text+0x4847): In function `bkref2_':
: undefined reference to `__mth_i_dlog'
../lib/libwsmp64.a(kl.o)(.text+0x61ef): more undefined references to
`__mth_i_dl
og' follow
../lib/libwsmp64.a(kl.o)(.data+0x40): In function `.C4_365':
: undefined reference to `pgf90_compiled'
../lib/libwsmp64.a(vkl.o)(.text+0x3dd): In function `lastvk2_':
: undefined reference to `__mth_i_dlog'
Could you please tell me how to solve those errors. They are not functions
in wsmp, but called by wsmp.
Thanks a lot!
