I'm trying to build our studies locally using MingW on Linux, but for some reason the symbols scsf_ are never present in the created dll-file. I've tried all kinds of different compilation and linking parameters, also the ones provided officially here https://www.sierrachart.com/index.php?page=doc/AdvancedCustomStudyInterfaceAndLanguage.php#RemoteCompilerParameters_32. x86_64-w64-mingw32-g++ -D _WIN64 -U NOMINMAX -march=x86-64 -mtune=x86-64 -O2 -shared -static -static-libgcc -static-libstdc++ -s -fno-rtti -fno-exceptions -std=gnu++11 {InputFiles} -o Output.dll -Wno-deprecated I'm building with wine64 x86_64-w64-mingw32-g++ ... Running the nm command on the dll just reports "no symbols". $ wine64 ~/Apps/cc/mingw64/bin/nm.exe strategy_64.dll Z:\home\nixos\Apps\cc\mingw64\bin\nm.exe: strategy_64.dll: no symbols It is also not possible to load the strategy in Sierra Chart. What are the compiler/linker/etc flags used by "Remote Build"? All my studies build, load and work correctly with remote build. |

Thank you for the answer! Unfortunately on my system this command doesn't produce a binary with symbols. I guess it could be related to compiler version, environment or something else. Would you mind sharing a build log with debugging enabled? Add -v -fverbose-asm -Q -save-temps to the command. If this path doesn't work I'll try compiling with clang instead.

i switched to clang with xwin (the authentic winsdk), because i had issues getting a debugger to work with mingw's dwarf versus pdb format sierrachart ?= /opt/sierrachart xwin ?= /opt/xwin CXX = clang++ CXXFLAGS += -target $(arch)-pc-windows-msvc -O3 -shared -fuse-ld=lld CXXFLAGS += $(addprefix -isystem, $(header)) LDFLAGS += $(addprefix -L, $(addsuffix /$(arch), $(library))) ifndef strip CXXFLAGS += -O0 -g -fstandalone-debug endif header += $(xwin)/splat/crt/include header += $(shell find $(xwin)/splat/sdk/include -maxdepth 1 -type d) header += $(sierrachart)/ACS_Source library += $(xwin)/splat/crt/lib library += $(shell find $(xwin)/splat/sdk/lib -maxdepth 1 -type d) src = $(wildcard *.cpp) aarch64 = $(src:.cpp=_arm64.dll) x86_64 = $(src:.cpp=_64.dll) default: aarch64 x86_64 aarch64: $(aarch64) x86_64: $(x86_64) %_arm64.dll: arch = aarch64 %_arm64.dll: %.cpp $(CXX) $(CXXFLAGS) $(LDFLAGS) -o $@ $^ $(LDLIBS) %_64.dll: arch = x86_64 %_64.dll: %.cpp $(CXX) $(CXXFLAGS) $(LDFLAGS) -o $@ $^ $(LDLIBS) clean: rm -f $(aarch64) $(aarch64:.dll=.lib) $(aarch64:.dll=.pdb) $(x86_64) $(x86_64:.dll=.lib) $(x86_64:.dll=.pdb) .PHONY: default aarch64 x86_64 clean to install the winsdk: xwin --accept-license --arch aarch64,x86_64 --cache-dir /opt/xwin --sdk-version 10.0.22621 splat --include-debug-libs --include-debug-symbols Date Time Of Last Edit: 2024-12-19 23:19:52
