Description
Describe the bug
Since commit 60ccc1f ("feat: support std::string_view in Value API"), simple example fails to linker error.
To Reproduce
Steps to reproduce the behavior:
- Install latest jsoncpp (using Ubuntu:24.04 Docker image in this test)
git clone https://github.com/open-source-parsers/jsoncpp.git
cmake -B build-jsoncpp jsoncpp
cmake --build build-jsoncpp --target install
- Example project:
CMakeLists.txt
project("Example")
add_executable(example main.cpp)
target_link_libraries(example jsoncpp)main.cpp
#include <iostream>
#include <json/json.h>
int main()
{
Json::Value root;
root["key"] = "value";
std::cout << root.isMember("key") << '\n';
root.removeMember("key");
return 0;
}- Try build
cmake -B build-example example && cmake --build build-example - Build fails with linker error
: && /usr/bin/c++ -rdynamic CMakeFiles/example.dir/main.cpp.o -o example -ljsoncpp && :
/usr/bin/ld: CMakeFiles/example.dir/main.cpp.o: in function `main':
main.cpp:(.text+0x6c): undefined reference to `Json::Value::operator[](std::basic_string_view<char, std::char_traits<char> >)'
/usr/bin/ld: main.cpp:(.text+0xb7): undefined reference to `Json::Value::isMember(std::basic_string_view<char, std::char_traits<char> >) const'
/usr/bin/ld: main.cpp:(.text+0x105): undefined reference to `Json::Value::removeMember(std::basic_string_view<char, std::char_traits<char> >)'
collect2: error: ld returned 1 exit status
ninja: build stopped: subcommand failed.
Expected behavior
- Build successful. Works before commit 60ccc1f
Desktop (please complete the following information):
- OS: Ubuntu 24.04
- Meson version 1.3.2 (repeats with both meson and cmake builds)
- Ninja version 1.11.1
Additional context
- Extracting
"key"tostd::string,std::string_vieworchar*constant does not resolve the issue.
