Hello,
I'm trying to create a basic console application on Windows:
#include <stdio.h>
#include <string.h>
int main() {
char buffer[1024];
fprintf(stdout, "Enter text: ");
if (fgets(buffer, sizeof(buffer), stdin)) {
buffer[strcspn(buffer, "\n")] = '\0';
fprintf(stdout, "You entered: \"%s\"\n", buffer);
} else {
fprintf(stderr, "Error reading input.\n");
return 1;
}
return 0;
}
I compile this with MinGW and bundle it into an app with makeappx.exe
from the Windows SDK:
$ x86_64-w64-mingw32-gcc SimpleApp/simple.c -o SimpleApp/simple.exe
$ /cygdrive/c/Program\ Files\ \(x86\)/Windows\
Kits/10/bin/10.0.26100.0/x64/makeappx pack /d SimpleApp /p Simple.msix
...
Package creation succeeded.
Finally I install this in Powershell using:
PS > Add-AppxPackage -Path .\Simple.msix -AllowUnsigned
PS > Get-AppxPackage -Name "SimpleApp.Simple" | Select-Object
-ExpandProperty InstallLocation
C:\Program Files\WindowsApps\SimpleApp.Simple_1.0.0.0_x64__enwe9x4v0qrt
In Windows Terminal / cmd.exe, this seems to work great.
The problem is that an execution alias does not work under Cygwin / MinTTY:
$ simple_console_app.exe # alias requested in AppxManifest.xml
<hangs in fgets() - nothing is printed to terminal>
However using the application directly from its install path works fine:
$ /cygdrive/c/Program\
Files/WindowsApps/SimpleApp.Simple_1.0.0.0_x64__enwe9x4v0qrtw/simple.exe
Enter text: 1+1
You entered: "1+1"
Is this a conpty or related issue? I don't know how Windows implements
its app execution aliases.
For reference, this is my AppxManifest.xml:
