For sometime I did not update gretl files from CVS, and now I not able to build.
I believe it was by changes regarding date/time functions.
Here is the output:
make: Leaving directory `/home/helio/gretl/lib'
make -C cli
make: Entering directory `/home/helio/gretl/cli'
: undefined reference to `g_get_monotonic_time'
collect2: ld returned 1 exit status
make: *** [gretlcli] Error 1
make: Leaving directory `/home/helio/gretl/cli'
make: *** [cli] Error 2
Searching in Internet for g_get_monotonic_time, I see that it belongs in GTK+, but even in GTK 2, is there.
Well, there is now a CentOS 7 released, maybe if I upgrade, this gets solved.
