[Flex-help] Compiling flex 2.6.4 from source

[David S. <arc...@da...>]

Hi,

I'm compiling flex 2.6.4. on my ancient armv5tl machine. The 
autoconfigure and configure seem to work fine. However when I try and make:

/bin/sh ../libtool  --tag=CC   --mode=link gcc  -g -O2 -version-info 
2:0:0  -o libfl.la -rpath /usr/local/lib libmain.lo libyywrap.lo  -lm
libtool: link: rm -fr  .libs/libfl.so .libs/libfl.so.2 .libs/libfl.so.2.0.0
libtool: link: gcc -shared  -fPIC -DPIC  .libs/libmain.o 
.libs/libyywrap.o   -lm  -g -O2   -Wl,-soname -Wl,libfl.so.2 -o 
.libs/libfl.so.2.0.0
libtool: link: (cd ".libs" && rm -f "libfl.so.2" && ln -s 
"libfl.so.2.0.0" "libfl.so.2")
libtool: link: (cd ".libs" && rm -f "libfl.so" && ln -s "libfl.so.2.0.0" 
"libfl.so")
libtool: link: ar cr .libs/libfl.a  libmain.o libyywrap.o
ar: error while loading shared libraries: libfl.so.2: cannot open shared 
object file: No such file or directory

However:

file ./src/.libs/libfl.so.2.0.0 gives

./src/.libs/libfl.so.2.0.0: ELF 32-bit LSB shared object, ARM, EABI5 
version 1 (SYSV), dynamically linked, 
BuildID[sha1]=b8851f7a64c9d9d1794b4b91a0126023b5cf0fa2, with debug_info, 
not stripped

So a correct libfl.so.2.0.0 library does exist in the build package.

So my problem seems circular, I need to install flex to get the libfl 
used by much of the build environment, but I can compile flex to give 
the libfl, because the make depends on libfl. So do I need to by hand 
copy the libfl into /usr/local/lib? That seems a bit of a hack. Is there 
a better way to resolve this dependancy?

Thanks,

David Summers.
