TWS API Linux - 分段错误 - __bid64_to_string

Question

开箱即用地运行 Cpp 示例客户端。

\n

我收到分段错误。

\n

0x00005555555efba6 in __bid64_to_string ()

\n

已将此函数来源到客户端文件Decimal.h

\n

extern "C" void __bid64_to_string(char*, Decimal, unsigned int*);

\n

这可能与API文档提到的浮点库有关：Intel\xc2\xae Decimal Floating-Point Math Library

\n

\n

我已经使用 WSL Ubuntu 20.04.05 检查了它是否安装在我的 ubuntu 版本上

\n

查看makefile：

\n

CXXFLAGS=-pthread -Wall -Wno-switch -Wpedantic -Wno-unused-function -std=c++11\nROOT_DIR=../../../source/cppclient\nBASE_SRC_DIR=${ROOT_DIR}/client\nINCLUDES=-I${BASE_SRC_DIR} -I${ROOT_DIR}\nSHARED_LIB_DIRS=${BASE_SRC_DIR}\nSHARD_LIBS=libTwsSocketClient.so\nTARGET=TestCppClient\n\n$(TARGET)Static:\n    $(CXX) $(CXXFLAGS) $(INCLUDES) $(BASE_SRC_DIR)/*.cpp ./*.cpp $(BASE_SRC_DIR)/lib/libbid.a -o$(TARGET)Static\n\n$(TARGET):\n    $(CXX) $(CXXFLAGS) $(INCLUDES) ./*.cpp $(BASE_SRC_DIR)/lib/libbid.so $(SHARED_LIB_DIRS)/$(SHARD_LIBS) -o$(TARGET)\n\nclean:\n    rm -f $(TARGET) $(TARGET)Static *.o\n\n

\n

有趣的部分 - 我可以在 Windows 上编译完全相同的代码，在 win32 中编译 VScode。

\n

我尝试用 gcc 强制执行 32 位。添加-m32。

\n

执行此操作时，编译器会显示许多抱怨：

\n

 1974 |  printf("Soft dollar tiers (%lu):", tiers.size());\n      |                             ~~^     ~~~~~~~~~~~~\n      |                               |               |\n      |                               |               std::vector<SoftDollarTier>::size_type {aka unsigned int}\n      |                               long unsigned int\n      |                             %u\n

\n

我注释掉了这些包含 %lu 的函数，因为在主应用程序中不需要它们。

\n

再次编译，这次我们与 TWS API 一起打包的库（英特尔十进制浮点数学库）出现错误，这些库随原始 TWS 安装一起提供，并定位：

\n

/source/cppclient/client/lib/libbid.a\n

\n

/usr/bin/ld: i386:x86-64 architecture of input file `../../../source/cppclient/client/lib/libbid.a(bid64_string.o)\' is incompatible with i386 output\n/usr/bin/ld: i386:x86-64 architecture of input file `../../../source/cppclient/client/lib/libbid.a(bid128_2_str_tables.o)\' is incompatible with i386 output\n/usr/bin/ld: i386:x86-64 architecture of input file `../../../source/cppclient/client/lib/libbid.a(bid_decimal_data.o)\' is incompatible with i386 output\n

\n

win32 运行这个 vscode 就很好了。

\n

使用 ```gcc -m64`` 运行

\n

再次获取段错误：

\n

Thread 1 "TestCppClientSt" received signal SIGSEGV, Segmentation fault.\n0x00005555555efba6 in __bid64_to_string ()\n(gdb) bt\n#0  0x00005555555efba6 in __bid64_to_string ()\n#1  0x00007fffffffd940 in ??

\n

不确定此时可能是什么 - WSL 和在 Windows 上运行 ubuntu - 该进程管理内存？ubuntu和windows有冲突吗？

\n

此时 - 我还能检查/排除哪些问题？

\n

谢谢

好吧，终于找到了英特尔浮点数学库所在的位置（名为：）libintelrdfpmath-dev，这与按原样使用 TWS API 附带的库（位于目录：）形成鲜明对比~/IBJts/source/cppclient/client/lib/libbid.a ：

我编辑了makefile该库的路径，现在是哪个？

我添加了

/usr/lib/x86_64-linux-gnu/libbidgcc000.a到我的 make 文件。

我的 makefile 如下所示：

CXX=g++
CXXFLAGS=-pthread -Wall -Wno-switch -Wpedantic -Wno-unused-function -std=c++11
ROOT_DIR=../../../source/cppclient
BASE_SRC_DIR=${ROOT_DIR}/client
INCLUDES=-I${BASE_SRC_DIR} -I${ROOT_DIR}
SHARED_LIB_DIRS=${BASE_SRC_DIR}
SHARD_LIBS=libTwsSocketClient.so
TARGET=TestCppClient

$(TARGET)Static:
$(CXX) $(CXXFLAGS) $(INCLUDES) $(BASE_SRC_DIR)/*.cpp ./*.cpp /usr/lib/x86_64-linux-gnu/libbidgcc000.a -o$(TARGET)Static

$(TARGET):
$(CXX) $(CXXFLAGS) $(INCLUDES) ./*.cpp $(BASE_SRC_DIR)/lib/libbid.so $(SHARED_LIB_DIRS)/$(SHARD_LIBS) -o$(TARGET)

clean:
rm -f $(TARGET) $(TARGET)Static *.o

请求的实时条形图、小数位看起来符合预期，最重要的是没有分段错误。

希望这能解决其他问题。
