I installed eclipse Kepler 4.3 SR2. I installed the latest release of buildroot 2014.08 and created a output target and set it to integrate with buildroot. I installed the plugin from http://buildroot.org/downloads/eclipse/kepler-sr2 I created an empty C static library project and choose the buildroot toolchain (it appears there in the list as expected). I added a simple C file and tried to build the project. This is what I received in the console: 10:39:38 **** Incremental Build of configuration debug for project TestStaticLib2 **** make all Building file: ../Test.c Invoking: Buildroot X86_64 C Compiler (/home/oded/dev/buildroot-2014.08/output) /home/oded/dev/buildroot-2014.08/output/host/usr/bin/x86_64-buildroot-linux-gnu-gcc -O0 -g3 -Wall -c -fmessage-length=0 -MMD -MP -MF"Test.d" -MT"Test.d" -o "Test.o" "../Test.c" Finished building: ../Test.c Building target: TestStaticLib2.a Invoking: Buildroot X86_64 C Linker (/home/oded/dev/buildroot-2014.08/output) /home/oded/dev/buildroot-2014.08/output/host/usr/bin/x86_64-buildroot-linux-gnu-gcc -o "TestStaticLib2.a" ./Test.o /home/oded/dev/buildroot-2014.08/output/host/usr/x86_64-buildroot-linux-gnu/sysroot/usr/lib/../lib64/crt1.o: In function `_start': (.text+0x20): undefined reference to `main' collect2: error: ld returned 1 exit status make: *** [TestStaticLib2.a] Error 1 10:39:38 Build Finished (took 228ms) As you can see it tried to create an executable and not a static library and failing because it cannot find the main symbol. Where I go to project properties. To C/C++ Build. Settings and Build Artifact tab, in the artifact type list I can only see executable and shared library. There is no artifact for static library. Any ideas ?

I am creating a simple project based on the eclipse project wizards: 1. File -> New -> C++ Project 2. Static Library -> Empty Project -> Choose Buildroot x86_64 toolchain 3. Finish Once the project is created, I go to Project properties -> C/C++ Build -> Settings -> Build Artifacts. I see there that there is only a shared object and executable option. No static library. When I go to the toolchain editor, I can see the list of tools (compiler, linker, etc.) but I don't see the archiver tool.. thus.. obviously that?s why we cannot build the static library. I will maybe try to uninstall everything and reinstall and see if it helps...

Could you give a few more details about how you're building your static library? Are you using an autotools based project, a Makefile based project, or a "managed build" project (where Eclipse takes care of the build system) ? M?lanie has tested a "managed build" project for a static library, and apparently, it worked fine. So maybe you're using your own Makefile or autotools based build system? Thanks!
