bhaskara-r · 10-14-2014, 12:41 AM

hi

i have the makefile which is compiling successfully in gcc version 2.95.3 20010315 (release).

But if i compile the same in gcc version 4.4.2 (GCC). It shows the following error

"ld: unrecognized option "
"ld: use the --help option for usage information"

Please help me to solve it

how do you expect help without giving any information?

hi

i have the makefile

pruAlarm:cPruAlmTsk.o cPruAlmMgr.o cPruAlmList.o $L/pruBase.lib
$(LD) $(LDFLAGS) cPruAlmTsk.o cPruAlmMgr.o cPruAlmList.o $L/pruBase.lib\
-o pruAlarm

when i am giving make pruAlarm in the "gcc version 2.95.3 20010315 (release)" it is compiling fine and executable is created.

But if i give the same make pruAlarm in "gcc version 4.4.2 (GCC)". It Shows the followinn Error

"ld: unrecognized option"
"ld: use the --help option for usage information".

Still what info u need.

what is in LDFLAGS, what is that unrecognized options, what is the full output? ....

bhaskara-r · 10-14-2014, 02:10 AM

LDFLAGS = -Wall

Unrecognized option is -Wall

pan64 · 10-14-2014, 02:17 AM

-Wall itself should not cause any problem

the differences in gcc 2 and gcc 4
are --- well, Astronomical

i would NOT expect old code from the 1990's to build in the 2000 TEENS

you will likely need to do a full rewrite of the code base

well you can go back in time a bit in the changelog
