Description
I'm trying to build Nvidia's jetson multimedia api samples with Buck so I can integrate into a project but wanted to test things out first. I built the BUCK file (below) from their Rules.mk file and I believe everything is the same.
cxx_binary(
name = "nvenc",
srcs=glob([
"samples/01_video_encode/*.cpp",
"samples/common/classes/*.cpp"
]),
deps = [],
include_directories = [
"include",
"include/libjpeg-8b",
"samples/common/algorithm/cuda",
"samples/common/algorithm/trt",
"/usr/local/cuda/include",
"/usr/include/aarch64-linux-gnu",
"/usr/include/libdrm",
"/usr/include/opencv4"
],
linker_flags=[
"-pthread",
"-lv4l2",
"-lEGL",
"-lGLESv2",
"-lX11",
"-ldrm",
"-lnvbuf_utils",
"-lnvjpeg",
"-lnvosd",
"-lcudart",
"-lcuda",
"-L/usr/local/cuda/lib64",
"-L/usr/lib/aarch64-linux-gnu",
"-L/usr/lib/aarch64-linux-gnu/tegra"
],
visibility = [ "PUBLIC" ]
)
Linking fails though with hundreds of undefined reference errors to the libraries I'm trying to link to. Looking at the linker.argsfile, it shows:
-o
buck-out/gen/nvenc
-pthread
-lv4l2
-lEGL
-lGLESv2
-lX11
-ldrm
-lnvbuf_utils
-lnvjpeg
-lnvosd
-lcudart
-lcuda
-L/usr/local/cuda/lib64
-L/usr/lib/aarch64-linux-gnu
-L/usr/lib/aarch64-linux-gnu/tegra

and I notice all the libraries are before all the .o files. If I move the libraries to the end and manually run g++ with these args, it builds successfully. Is there a param I'm setting wrong or not setting in my buck file that can fix this?
