[Genesis-sim-users] help with compiling Genesis 2.4 on RHEL-6 system

[Susan C. <su...@he...>]

Hi,

I'm attempting to compile Genesis 2.4 from source in response to one of 
our users, and am hitting a wall here.

To summarize, I did a
./configure --prefix=/some/path/here

The configure went fine (config output appended at the end of this 
message).
The subsequent make failed. The first error was in the 'sys' subdirectory:

$ /usr/local/GCC/5.3.0/bin/gcc -O2 -D__NO_MATH_INLINES -DBSD -DLinux 
-lfl -DBSD -o code_lib code_lib.c
/tmp/ccLCiLkb.o: In function `main':
code_lib.c:(.text.startup+0x0): multiple definition of `main'
/usr/lib/../lib64/libfl.a(libmain.o):(.text+0x0): first defined here
/usr/lib/../lib64/libfl.a(libmain.o): In function `main':
(.text+0xb): undefined reference to `yylex'
collect2: error: ld returned 1 exit status

Any ideas what is going on? It seems to be related to the flex library. 
We have the following flex libraries installed:

flex-2.5.35-9.el6.x86_64
flex-devel-2.5.35-9.el6.x86_64

Any suggestions for how to proceed? Much appreciated.
Susan
