entry-point

问题 How do you build a C program that includes the entry point on Mac OS X? I want to build: start() { /* exit system call */ asm("movl $1,%eax;" "xorl %ebx,%ebx;" "int $0x80" ); } but when I run: gcc -nostdlib min.c I always get: ld: could not find entry point "start" (perhaps missing crt1.o) collect2: ld returned 1 exit status The one other attempt I made just to see what it was doing was run: gcc -nostdlib -c min.c && otool -tV min.o And the output was: (__TEXT,__text) section _start:

问题 I have a requirement to have a background process using Application, while also having a UiApplication through an alternative entry point. Now, everything works great and I'm able to communicate between them fine, apart from when it comes to telling the UiApplication to close from the background process. I've tried a number of methods: UiApplication.getUiApplication().requestClose() doesn't work. I've tried setting a boolean value to true, which the UiApplication checks every second to see if

问题 I am trying to match the host UID with container UID as below. Dockerfile RUN addgroup -g 1000 deploy \ && adduser -D -u 1000 -G deploy -s /bin/sh deploy USER deploy COPY entrypoint.sh / ENTRYPOINT ["/entrypoint.sh"] CMD ["php-fpm7","-F"] entrypoint.sh whoami # it outputs `deploy` # Change UID of 'deploy' as per host user UID HOST_CURRENT_USER_ID=$(stat -c "%u" /var/www/${PROJECT_NAME}) if [ ${HOST_CURRENT_USER_ID} -ne 0 ]; then gosu root usermod -u ${HOST_CURRENT_USER_ID} deploy gosu root

问题 I know that this question has been asked a lot, but none of the solutions seem to work for me. That or I am just incompetent and need to have my hand held through this problem (most likely solution). I looked through all of the classes, and all the build actions are set to compile, so I have no idea what could have gone wrong. Any help? Additional Details: I have been coding the starting of a game, and everything was going good until I got this error: Program does not contain a static 'Main'

问题 I am beginning to learn to write some low-level software for micro-controllers, and I've started studying linker scripts. I don't really get the meaning of the ENTRY command in this context. Since most micro-controllers start execution at a predetermined address, what difference does it make which entry point we choose in the linker script? 回答1: ENTRY() is an ELF feature that basically just sets the program entry address in the ELF header of your executable. This address may differ from the

问题 I compile following C program on lubuntu 12.10 with anjuta int main() { return 0; } the file name is foobar then I open up terminal and write command ndisasm foobar -b 32 1>asm.txt (disassemble foobar with 32 bit instruction option and save disassembled result to asm.txt) I open up asm.txt there are many 0x0000 and miss-understandable code. the instruction jg 0x47(0x7F45) on 0x00000000 and dec esp(0x4C) on 0x00000002 seems ELF file format signature. (because the hex code 0x454c46 is 'ELF' in

问题 I have been trying to call a DLL function in my VBA project but I keep getting this error message: Run-time error '453': Can't find DLL entry point "CheckStatus" in "Power.dll" Here is the definition for the DLL in the C++ file: #define CLASS_DECLSPEC extern "C" __declspec(dllexport) CLASS_DECLSPEC int __stdcall CheckStatus(); And here is how I'm trying to declare it and call it in VBA: Public Declare Function CheckStatus Lib "Power.DLL" () As Long Dim test As Long test = CheckStatus And then

问题 I am looking for the signature of mainCRTStartup. Is it : int mainCRTStartup( int argc, char *argv[] ) Or something else ? I find it so irritating that microsoft isn't even able to give the définition of their own entry points... Thanks for your help. 回答1: In the crtexe.c file, distributed with VisualStudio, you can see the definition. It is: int mainCRTStartup(void); The command line is not obtained as an argument to the entry point, but recovered by using the function GetCommandLine() . 来源：

问题 I have a problem I've been struggeling with for a full week now, and I'm not able to solve it by myself. I've been googeling, and searching in all kind of forums... I have found lots of "this might work", tried it, but no, no success. If anyone have any clue, please, please, help me! I'v got, from an external source, lots of classes and functions written in VB that I need to be able to use from a C++ application. My first though was: no problem, I turn the VB code into a dll, and load it from

问题 I'm trying to build the Windows version of my app. The program compiles and runs fine on Qt Creator but when I try to run it standalone it throws the following error: The procedure entry point _Z17qt_message_output9QtMsgTypePKc could not be located in the dynamic link library QtCore4.dll I have all the necessary dlls in my application folder and they are the same ones that came with the binaries I've downloaded from the Qt's website. This error is driving me crazy for I can't seem to find any
