I am trying to cross compile lftp-4.3.5 for my arm based board. I executed the configure file as:
"./configure --host=arm-montavista-linux CXX=arm-montavista-linux-gnueabi-g++ CC=arm-montavista-linux-gnueabi-gcc --with-openssl=/abcd/xxx/yyy/ssl with_included_readline=no"
I had to modify the configure file a bit. I added "i_cv_posix_fallocate_works=yes" coz I was getting errors like
checking for pty.h... yes
checking for library containing openpty... -lutil
checking for _getpty... configure: error: in `/home/xxxx/yyyy/lftp-4.3.5':
checking whether posix_fallocate() works... no
configure: error: cannot run test program while cross compiling
See `config.log' for more details
I could not get the solution for this so I modified it like this and got rid of this blockage.
Now it was asking for readline library, I downloaded the lib source code (readline-6.2) and cross compiled it. while running make file, make script was not taking the cross-compiled libreadline.a file from given location (I added --libdir path while running configure). Anyhow I was able to provide this lib to make script, but when scrip read this lib, it threw many errors as:
/bin/sh ../libtool --silent --tag=CXX --mode=link arm-montavista-linux-gnueabi-g++ -O2 -Wall -Wwrite-strings -Woverloaded-virtual -fno-exceptions -fno-rtti -fno-implement-inlines -s -o lftp lftp.o complete.o lftp_rl.o attach.o liblftp-jobs.la -lreadline -lutil -ldl

Now: 1. If anybody could help me figuring out the issue here? 2. or by any mean I could skip the addition of this readline lib? ('--with-readline=no' option not configured in config file).
I am trying to cross-compilation since 4-5 days and yet hanging with this. Anybody would help me pls.
Thanks, Rahul
