masm error no program entry point

To get extended error information, application can call GetLastError API: CODE ; Begin code segment _main PROC ; Main entry point into program. Microsoft added the textequ directive starting with MASM 6.0. The purpose of the “=” directive lar section of code, introducing a bug into your program. Enables error messages for code constructs that violate the requirements for Marks the end of a module and, optionally, sets the program entry point to.

<<, sizeof, etc.), registers should have $ prefix ($eax for example). If you want to watch memory on address you should check "Address" checkbox on the right. Output format is determined in the first drop-down menu (format Smart trying to choose the most suitable type of display). To watch contents of array specify the number of elements in the array in "array size" field, masm error no program entry point. To remove watches click right mouse button on it and choose "Delete watch" or press Del button. In Windows watching variables from .rodata section you should display them as address. Values of registers and expressions refreshes by jumping on next instruction.
  • Also when you run the debugger you see "GDB command" widget on the bottom of SASM. Http post+internal server error 500 its help you can perform any gdb command pressing Enter key. Commands and their results will be showed in log widget. Previous commands available by pressing up and down keys. If you press Enter with empty command, last command will be performed. Results of performing commands synchronize with current debugging line highlighting and with state of windows, which shows memory and registers. You can use "Print" option - if it is checked, result of command performing printing immediately ("p" command adds to input) (handy for masm error no program entry point quick evaluation of the expression (for example, as a calculator)). In expressions you can use any operator of C language (*, &, +, - , /, %, !, >, &, ld}

    SASM (SimpleASM) - simple Open Source crossplatform IDE for NASM, MASM, masm error no program entry point, GAS, FASM assembly languages.

    In SASM you can easily develop and execute programs, written in NASM assembly language. Enter code in form and simply run your program. Enter your input data in "Input" docking field. In "Output" field you can see the result of the execution of the program. Wherein all messages and compilation errors will be shown in the form on the bottom. You can save source or already compiled (exe) code of your program to file and load your programs from file.

    SASM supports working with many opened projects – new files are opened and created in new tabs. At the exit from SASM current set of opened files saved. At the next start you can restore previous session. In settings you can set font, color scheme and initial text. SASM is translated into Russian and English. All dialog windows in SASM is docking - you can choose one of many variants of their position. Standard "Edit" menu extended with abilities to comment/uncomment piece of source code and to create/delete indent with 4 spaces (Tab/Shift+Tab).

    Starting with version 2.2 it is possible to reassign the hotkeys. File with them located on the path "Linux/share/sasm/keys.ini" ("/usr/share/sasm/keys.ini" if SASM was installed) on Linux and on the path "Windows/keys.ini" ("{folder where SASM was installed}/keys.ini") on Windows.

    Starting with version 2.3 SASM supports 2 modes - x64 and x86. You can choose mode in settings on "Build" tab. "io.inc" macro library works with both modes. Also there you can change assembler and linker options.

    Starting from version 3.0 you can choose one of four assemblers - NASM, MASM, GAS, FASM in settings on "Build" tab. Also there you can choose your own assembler or linker filling path to them. Thus you can setup SASM on work with any assembler filling path to assembler and, if needed, to linker and filling options for assembling and linking. But debugging and highlighting may work little incorrectly. To realize full support of new assembler, it is needed to implement Assembler abstract class by analogy with already implemented assemblers.

    All assemblers (excluding MASM) are included in SASM (on Linux they should be installed) and you can use they right away after their choice, masm error no program entry point. MASM assembler can not be included in the assembly because of its license. To use it, you should install MASM on your computer from site http://www.masm32.com/ and specify path to MASM assembler (ml.exe, path usually "C:/masm32/bin/ml.exe") and to MASM linker (link.exe, path usually "C:/masm32/bin/link.exe") in according fields on "Build" tab in settings.

    SASM contains folder for include files - "Linux/share/sasm/include/" ("/usr/share/sasm/include/" if SASM was installed) on Linux and on the path "Windows/include/" ("{folder where SASM was installed}/include/") in Windows. But for MASM this folder does not work - in this case you should use absolute path to include files.

    "io.inc" macro library for NASM

    SASM includes crossplatform input/output library "io.inc". It contains I/O macro and 2 additional macro for NASM: CMAIN - entry point and CEXTERN for invoking functions, located in C language libraries ("CEXTERN printf" for example). Definitions of all macro you will see on SASM site: http://dman95.github.io/SASM/

    A little bit about the debugger:

    As the debugger SASM used gdb. In the distribution under Windows it included in the package. In Linux, you must install this package. Attention! Before debugging make all functions formed frames (mov ebp, esp). This rule should be done for all functions, including main. Also, if gcc used as a linker, masm error no program entry point, then the program masm error no program entry point point should be marked with global label _main (Windows) or main (Linux) or CMAIN from "io.inc". Otherwise entry point should be marked with start label. Other labels for the entry point can not be used. Program code should be contained only in ".text" section (".code" for MASM). If you use other names for the code section, then the debugger correct work is not guaranteed. To run the debugger click "Debug" item in "Debug" menu or press F5. Now you can debug your program.

    • You can toggle breakpoint, clicking on line number or pressing F8 with cursor on line number, on which you want to suspend your program execution.
    • "Continue" command (F5) continues execution to breakpoint or to the end of your program.
    • "Step into" command (F11) goes to next instruction possible entering functions.
    • "Step over" command (F10) goes to next instruction skipping functions.
    • "Show registers" error saving db5 (Ctrl+R) shows window with values of CPU masm error no program entry point memory" command (Ctrl+M) shows window to watch variables or memory on random address. Typing name of variable, address or any expression over text "Add variable." and size (b - byte (1), w - word (2), d - double word (4), q - quad word (8)), in "Value" field you will see value of expression. Also you can add variable from code, clicking right mouse button on line with variable and choose "Watch". In expressions you can use any operator of C language (*, &, +, - *, /, %, !, >, &, masm error no program entry point
