Hi all,

I’m new to Legato.  
I have been working on some embedded Linux device before.  
I have an C application which linked to libcurl library on my current device and I want to make it run on Legato platform.  
So is it possible to compile libcurl (or any 3rd C/C++ library in general) as a Legato component and my application as a Legato application then install and run it on my MangOH dev board? I would really appreciate if you have any tutorial related to this subject.

I’m using Developer Studio 4.1 (Legato 16.4) on Ubuntu 16.04 64 bits.

Thank a lot for your help,

I posted this on the sierra forum coping here

## Makefile bits this is abuse of makefile but you will get some ideas how to do it

PREFIX=/usr

LEGATO\_OUTPUT = \_build\_linphone/wp85/build  
TARGET = wp85  
TOOLCHAINPRE = ${WP85\_TOOLCHAIN\_DIR}/arm-poky-linux-gnueabi

SYSROOT = $(shell $(TOOLCHAINPRE)-gcc -print-sysroot)  
PWD = $(shell pwd)

CC = $(TOOLCHAINPRE)-gcc  
CXX = $(TOOLCHAINPRE)-g++  
LD = $(TOOLCHAINPRE)-ld  
AR = $(TOOLCHAINPRE)-ar  
RANLIB = $(TOOLCHAINPRE)-ranlib

sqlite-autoconf\_OPT = CFLAGS="-DSQLITE\_SECURE\_DELETE -DSQLITE\_ENABLE\_UNLOCK\_NOTIFY"

sqlite-autoconf:  
(if [! -d build/$@];then   
mkdir build/$@;   
fi;  
cd $@;   
./$($@\_CPTH)configure --prefix=/usr --libdir=/usr/lib CC=$(CC) CXX=$(CXX) --host=arm-poky-linux-gnueabi $($@\_OPT))  
make -C $@  
make -C $@ DESTDIR=$(SYSROOT) install  
make -C $@ DESTDIR=$(PWD)/output install

install:  
mkdir -p $(LEGATO\_OUTPUT)  
(cd output && rsync -avPR --exclude=_.a --exclude=_.la usr/lib usr/bin usr/sbin …/$(LEGATO\_OUTPUT)/)
