TouchGFX和VisualGDB中的链接器错误要如何解决？

问答对人有帮助，内容完整，我也想知道答案 0 我正在尝试使用带有硬件 FPU、TouchGFX 和 VisualGDB 的 STM32F7 设置系统。我可以编译，但是在链接期间出现以下错误： TouchGFXConfiguration.cpp Linking VisualGDB/Debug/Ozonclean... c:/sysgcc/arm-eabi/bin/../lib/gcc/arm-none-eabi/9.2.1/../../../../arm-none-eabi/bin/ld.exe: VisualGDB/Debug/TouchGFXConfiguration.o: in function `FrontendApplication::handleTickEvent()': Z:/Progetti_in_corso/OZONCLEAN/FW/Rev00/TouchGFX/gui/include/gui/common/FrontendApplication.hpp:18: undefined reference to `Model::tick()' c:/sysgcc/arm-eabi/bin/../lib/gcc/arm-none-eabi/9.2.1/../../../../arm-none-eabi/bin/ld.exe: VisualGDB/Debug/TouchGFXConfiguration.o: in function `FrontendHeapBase::gotoStartScreen(FrontendApplication&)': Z:/Progetti_in_corso/OZONCLEAN/FW/Rev00/TouchGFX/generated/gui_generated/include/gui_generated/common/FrontendHeapBase.hpp:75: undefined reference to `FrontendApplicationBase::gotoMainScreenNoTransition()' c:/sysgcc/arm-eabi/bin/../lib/gcc/arm-none-eabi/9.2.1/../../../../arm-none-eabi/bin/ld.exe: VisualGDB/Debug/TouchGFXConfiguration.o: in function `FrontendHeap::getInstance()': Z:/Progetti_in_corso/OZONCLEAN/FW/Rev00/TouchGFX/gui/include/gui/common/FrontendHeap.hpp:56: undefined reference to `__dso_handle' c:/sysgcc/arm-eabi/bin/../lib/gcc/arm-none-eabi/9.2.1/../../../../arm-none-eabi/bin/ld.exe: VisualGDB/Debug/TouchGFXConfiguration.o: in function `FrontendHeap::FrontendHeap()': Z:/Progetti_in_corso/OZONCLEAN/FW/Rev00/TouchGFX/gui/include/gui/common/FrontendHeap.hpp:65: undefined reference to `FrontendApplication::FrontendApplication(Model&, FrontendHeap&)' c:/sysgcc/arm-eabi/bin/../lib/gcc/arm-none-eabi/9.2.1/../../../../arm-none-eabi/bin/ld.exe: Z:/Progetti_in_corso/OZONCLEAN/FW/Rev00/TouchGFX/gui/include/gui/common/FrontendHeap.hpp:65: undefined reference to `Model::Model()' c:/sysgcc/arm-eabi/bin/../lib/gcc/arm-none-eabi/9.2.1/../../../../arm-none-eabi/bin/ld.exe: VisualGDB/Debug/TouchGFXConfiguration.o:(.data._ZL12fontProvider+0x0): undefined reference to `vtable for ApplicationFontProvider' c:/sysgcc/arm-eabi/bin/../lib/gcc/arm-none-eabi/9.2.1/../../../../arm-none-eabi/bin/ld.exe: VisualGDB/Debug/TouchGFXConfiguration.o: in function `touchgfx_init': //SERVER-PC/Ufficio_tecnico/Progetti_in_corso/OZONCLEAN/FW/Rev00/TouchGFX/target/generated/TouchGFXConfiguration.cpp:40: undefined reference to `BitmapDatabase::getInstance()' c:/sysgcc/arm-eabi/bin/../lib/gcc/arm-none-eabi/9.2.1/../../../../arm-none-eabi/bin/ld.exe: //SERVER-PC/Ufficio_tecnico/Progetti_in_corso/OZONCLEAN/FW/Rev00/TouchGFX/target/generated/TouchGFXConfiguration.cpp:40: undefined reference to `BitmapDatabase::getInstanceSize()' c:/sysgcc/arm-eabi/bin/../lib/gcc/arm-none-eabi/9.2.1/../../../../arm-none-eabi/bin/ld.exe: //SERVER-PC/Ufficio_tecnico/Progetti_in_corso/OZONCLEAN/FW/Rev00/TouchGFX/target/generated/TouchGFXConfiguration.cpp:42: undefined reference to `touchgfx::Texts::setLanguage(unsigned short)' c:/sysgcc/arm-eabi/bin/../lib/gcc/arm-none-eabi/9.2.1/../../../../arm-none-eabi/bin/ld.exe: VisualGDB/Debug/TouchGFXConfiguration.o: in function `__static_initialization_and_destruction_0': //SERVER-PC/Ufficio_tecnico/Progetti_in_corso/OZONCLEAN/FW/Rev00/TouchGFX/target/generated/TouchGFXConfiguration.cpp:61: undefined reference to `__dso_handle' c:/sysgcc/arm-eabi/bin/../lib/gcc/arm-none-eabi/9.2.1/../../../../arm-none-eabi/bin/ld.exe: VisualGDB/Debug/TouchGFXConfiguration.o: in function `ApplicationFontProvider::~ApplicationFontProvider()': Z:/Progetti_in_corso/OZONCLEAN/FW/Rev00/TouchGFX/generated/fonts/include/fonts/ApplicationFontProvider.hpp:18: undefined reference to `vtable for ApplicationFontProvider' c:/sysgcc/arm-eabi/bin/../lib/gcc/arm-none-eabi/9.2.1/../../../../arm-none-eabi/bin/ld.exe: c:/sysgcc/arm-eabi/bin/../lib/gcc/arm-none-eabi/9.2.1/../../../../arm-none-eabi/lib/thumb/v7e-m+fp/hardlibc_nano.a(lib_a-init.o): in function `__libc_init_array': init.c:(.text.__libc_init_array+0x14): undefined reference to `_init' c:/sysgcc/arm-eabi/bin/../lib/gcc/arm-none-eabi/9.2.1/../../../../arm-none-eabi/bin/ld.exe: VisualGDB/Debug/Ozonclean: hidden symbol `__dso_handle' isn't defined c:/sysgcc/arm-eabi/bin/../lib/gcc/arm-none-eabi/9.2.1/../../../../arm-none-eabi/bin/ld.exe: final link failed: bad value Build failed: arm-none-eabi-g++.exe exited with code 1 collect2.exe: error: ld returned 1 exit status ========== Project Build Summary ========== Ozonclean built in 00:04 ========== Build: 0 Succeeded, 1 Failed ========== 如果我没有误解的话，链接器找不到引用“FrontendApplication”、“Model”和“BitmapDatabase”。我该如何纠正这个问题？ 0

答案对人有帮助，有参考价值 0 是的！添加 TouchGFX 生成的文件（generated/）、gui 文件（gui/）并记得链接合适的库（touchgfx/lib/core）并包括 gccstubs.cpp (touchgfx/config/gcc/) - 它有一些你需要的符号，比如 void* __dso_handle = (void*)NULL; 也许您应该从我们现有的使用 gcc 的 Makefile（选择任何应用程序模板）中获得一些灵感。
