SAP DB 7.4 build problems on Red Hat Linux 8.0

i'm having some problems compiling SAP DB 7.4.03.14 on Red Hat Linux 8.0.  
SAP DB build system requires Python v1.5.2 and Perl v5.005_03 but Red Hat
comes with Python v2.2 and Perl v5.8.0. compiling Python on RH8 is not a
problem but Perl is. Red Hat comes with gcc v3.2 which makes Perl
v5.005_03 configuration system fail. i wasn't able to fix this problem so
i had to compile Perl on a RH7.3 system and copy the binaries (Python
v1.5.2 bin directory has to be added to path and Perl v5.005_03 path has
to be assigned to TOOLSHELL in V74_03_14/initDev_SAPDB).

when trying to build the all.mac target i get the following error messages
(i can provide full typescript if needed):

  1)
    !dbmcli -s -R $INSTROOT inst_reg -k $INSTROOT -c

i'm trying to build the all.mac target but it fails apparently because of
subtarget failures: reginst.mac, cpc.mac, allpc.mac, sqlpy.mac,
loaderpy.mac, vls14_scan.l, lsxlib.lib, lserver.lnk, pyinst.mac,
allknl.mac, reginst-FULL.mac.

i also get lots of warning about deprecated variable and function use:
  + sys_errlist is deprecated; use strerror or strerror_r
  + sys_nerr is deprecated; use strerror or strerror_r
  + use of tmpnam is dangerous, better use mkstemp

the system uses flex v2.5.4a and GNU Bison v1.35.


has anyone managed to compile SAP DB 7.4 on Red Hat Linux 8.0?
