Hi All,

I amtrying to compile from the source the ovlfs program that I get from here ( I actually need it for my Live CD project). However following the instructions, both from the Live CD site which suggest to run ./build and from the instruction that comes with the source to use ./configure make and make install, I got the following error:

make[1]: Entering directory `/usr/src/ovlfs-2.0.1/mount'
making ovlmount
/usr/lib/gcc-lib/i486-slackware-linux/3.3.4/../../../../i486-slackware-linux/bin/ld: cannot find -lfl
collect2: ld returned 1 exit status
make[1]: *** [ovlmount] Error 1
make[1]: Leaving directory `/usr/src/ovlfs-2.0.1/mount'
make: *** [mount] Error 2

I check the Makefile under the directory mount and found the following command:

ovlmount: $(OVLFS_MOUNT_OBJ)
@echo making ovlmount
@$(CXX_FOR_TARGET) $(CFLAGS) -o ovlmount $(OVLFS_MOUNT_OBJ) $(LIB) -lfl


On the same Makefile I also found

CFLAGS ?= -g
INC ?= -I../lib
LIB ?= -L../lib -lasn

# If you have and use a real "lex", unset FLEX_FLAG.
FLEX_FLAG ?= -DFLEX
CFLAGS += $(FLEX_FLAG)

OVLFS_MOUNT_OBJ=\
lex.yy.o \
y.tab.o \
ovlmount.o

and from Rules.mk I found

AR_FOR_BUILD ?= ar
CC_FOR_BUILD ?= cc
CXX_FOR_BUILD ?= c++
LD_FOR_BUILD ?= ld

So I know that somehow the C++ compiler have failed to do what it supposed to do and it has something to do with the -lfl key. My question is what does it all mean ? I don't even know what the -lfl switch is supposed to do.

Can any C/C++ guru out there help me out on this one ?

Thanks a lot in advanced.

-lfl is a linker flag telling the linker to link with the libfl library. For instance if it is -lX11, that means link with libX11 (just add lib in front). check your system to see if you have a version of flex installed.

Thanks al lot J...it works...

I install the flex package, then my ovlfs compile works like a charm....

Thanks again
