This is a linker/loader question. For gcc toolchain, you could add RPATH
by linker with -Wl,-rpath=/usr/local/lib
for your case, e.g.:
g++ main.cpp -I /usr/local/include -L /usr/local/lib -l milvus_sdk -o output -Wl,-rpath=/usr/local/lib
Of course, you could also try to use the LD_LIBRARY_PATH
environment variable while running the application.
@matrixji Thanks for the reply. This solution doesn't solve the problem because all the dependencies are in the cmake_build directory. none of them are in the usr/local/lib directory, although when I open any .pc file in cmake_build directory it says that the libraries are in the /user/local/lib directory.
is that expected of build? or should all the dependencies be in the usr/local/lib directory?
I used this bash script to include all necessary libs and include files from the cmake_dir.
#!/bin/bash
CMAK_BIULD_DIR=/home/mohamed/Mohamed/HPCC/milvus-sdk-cpp/cmake_build
# Libs directories.
LIBS_DIR=$(find ${CMAK_BIULD_DIR} -type f -name '*.a' | sed -r 's|/[^/]+$||' |sort |uniq)
BUILD_LIBS_DIR=""
for DIR in $LIBS_DIR;
do BUILD_LIBS_DIR="$BUILD_LIBS_DIR -L$DIR"
done
# Libs names.
LIBS_NAMES=$(find ${CMAK_BIULD_DIR} -type f -name '*.a' -printf "%f\n")
BUILD_LIBS_NAMES=""
for NAME in $LIBS_NAMES;
do
TMP_NAME=${NAME#"lib"}
firstchar=${TMP_NAME:0:1}
if [[ $firstchar == "0" ]];then
continue
else
BUILD_LIBS_NAMES="$BUILD_LIBS_NAMES -l${TMP_NAME%".a"}"
fi
done
#Include direcotries.
INCLUDE_DIRS=$(find ${CMAK_BIULD_DIR} -type f -name '*.h' | grep include | sed 's/include.*/include/' |sort |uniq )
INCLUDE_FILES_DIR=""
for DIR in $INCLUDE_DIRS;
do INCLUDE_FILES_DIR="$INCLUDE_FILES_DIR -I$DIR"
done
#build the code.
g++ main.cpp ${INCLUDE_FILES_DIR} ${BUILD_LIBS_DIR} ${BUILD_LIBS_NAMES} -o output &> error.txt
But it will be better to install the dependencies to usr/local
during build, won't it?
I also tried adding -DBUILD_SHARED_LIBS=YES
during cmake from milvus-io/milvus-sdk-cpp#241 and it didn't work either.
Have same problem, I have both /usr/local/lib/libmilvus_sdk.a and /usr/local/include/milvus but cannot compile main.cpp, got nearly 10000 lines of undefined reference error after run: g++ -std=c++14 main.cpp -I /usr/local/include -L /usr/local/lib -l milvus_sdk -o output
Nobody cares about this project?
did you compile successfully under your environment? https://github.com/milvus-io/milvus-sdk-cpp/blob/master/DEVELOPMENT.md
did you compile successfully under your environment? https://github.com/milvus-io/milvus-sdk-cpp/blob/master/DEVELOPMENT.md
Yes. I followed the installation in DEVELOPMENT.md. This is what I run:
git clone https://github.com/milvus-io/milvus-sdk-cpp
cd milvus-sdk-cpp
git checkout main
make all-release
I checked I had both /usr/local/lib/libmilvus_sdk.a
and /usr/local/include/milvus
. And I also can run ./sdk_simple
. But when I run: g++ main.cpp -I /usr/local/include -L /usr/local/lib -l milvus_sdk -o output -Wl,-rpath=/usr/local/lib
or run the @abuelnasr0 's bash script above, still got the errors with 13000 lines.
Tell me if I do something wrong? Thank you
what operating system and gcc versions you are using?
could you share the error message?
and is there a reason you specify to use -std=c++14?
My OS is Ubuntu 20.04 and gcc version is 9.4.0 I tried both -std and not. but all return errors. This is the head and the end of the errors:

IMO, this is a code integration issue, we do tests/examples with CMake, and this is smooth for application integration with milvus-sdk-cpp, but if guys use GNU Makefile
to manually compile/link commands, the dependency may lost.
I'll try to provide some guide documentation based on Ubuntu. Maybe a couple of weeks later...
I installed milvus successfully and ran the simple example. but I want to use milvus from another directory. I tried this to build the program:
but I got nearly 10000 lines of
undefined reference
error because of the SDK dependencies. how to show the SDK dependencies that are in thecmake_build
directory to the linker?
