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, ---

Yes it can be done busy doing just that to include linphone for SIP VOIP … i build the package then install it into the sysroot and put the bits i want into a folder that i include in the adef. i even added a driver framework for legato audio in the legacy package … one of the packages i added was sqlite3.

Hi Greg, Thank you for your response. Could you be a little more specific about how doing it? I’m trying to doing it with Developper Studio by importing libcurl as a C/C++ project from Existing source. Then I choose Legato Application Framwork GCC as toolchain and Legato Application Framwork Builder as builder but the project couldn’t be built. Regards, Trung ---

You using linux or similar ?? i do it writing a make file from the console but it does work from the IDE [tested it for you] using linux as a dev platform helps as you can run the shell scripts. ---

When you want to build a non-legato project in DS, you need to choose Legato Linux GCC toolchain, and Make builder (Legato) as builder, to get something working. ---

Hi everyone, Please forgive me for taking so long to reply, I just came back from vacation yesterday. [quote=“daav”] When you want to build a non-legato project in DS, you need to choose Legato Linux GCC toolchain, and Make builder (Legato) as builder, to get something working.[/quote] Thank you it is working, well I have to do a manual configure to create a right Makefile but everything seems good. I can complie curl, json-c, …, copy them manually and make them run successfully in my MangOH board. ## [quote=“gregnietsky”]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)/) $(TOOLCHAINPRE)-strip $(LEGATO\_OUTPUT)/usr/bin/\* || true $(TOOLCHAINPRE)-strip $(LEGATO\_OUTPUT)/usr/sbin/\* || true $(TOOLCHAINPRE)-strip $(LEGATO\_OUTPUT)/usr/lib/\* || true ./mkadef \> linphone.adef mkapp -t $(TARGET) linphone.adef[/quote] Your Makefile seems good, that might be what I need to create a packaging .update for each library/app and install it in Legato platform. I’ll keep you informed about my tests.
