The GYRE Forums

Hi, I have MESA (the latest version) installed and it works well. I tried installing GYRE standalone. And after setting the
GYRE_ROOT directory, I get the following error when I try and compile it:

[shashi@localhost gyre]$ make
FC gyre.f90
LD gyre
/lib/../lib64/crt1.o: In function `_start':
(.text+0x20): undefined reference to `main'
collect2: error: ld returned 1 exit status
make[2]: *** [gyre] Error 1
rm gyre.o

Then I realized that when I installed the latest version of MESA, it also downloaded the latest version of GYRE - the same version you get
if you download GYRE standalone. I have the flag in the header file that is supposed to compile GYRE along with MESA set to YES, but when I install MESA and compile it, it doesn't seem as if it compiles GYRE. I tried running make in the gyre subdirectory within MESA and got the same result as above. Any thoughts would be appreciated. Thanks

Hi Shashi --

Can you try running 'make clean' and then 'make' again? There may be some stuff left over from a previous compilation attempt.

cheers,

Hello, on Fedora, I installed Gyre 5.1. In bash, I
export MESA_DIR=~/mesa
export MESASDK_ROOT=~/mesasdk
source ~/mesasdk/bin/mesasdk_init.sh
export GYRE=~/gyre
(ie. thjis is standalone GYRE)
cd $GYRE_DIR
make clean
make
That worked!
make test worked till the following:

TEST MESA model for delta Cephei star (non-adiabatic)...
...succeeded
TEST MESA model for Sun (non-adiabatic, diffusion vs. Eddington approxiation)...

Hi Shashi --

Looks like things are working OK now. The failed test is a known issue on Linux -- nothing to worry about.

cheers,

Hi, I also got the failed test to work following
cd test/nad/mesa/solar
make build_ref
Thanks for your help!
