That depends on which variant of toolchain you’re currently using. Both DWARF and SEH variants (which come starting from GCC 4.8.0) are only single-target. You can see it yourself by inspecting the directory structure of their distributions, i.e. they contain only the libraries with either 64- or 32-bit addressing, but not both. On the other … Read more
Here is an instruction how to install 32-bit and 64-bit Oracle Client on one machine. Follow the instruction, then it should work. Assumptions: Oracle Home is called OraClient11g_home1, Client Version is 11gR2 Download and install Oracle x86 Client, for example into C:\Oracle\11.2\Client_x86 Download and install Oracle x64 Client into different folder, for example to C:\Oracle\11.2\Client_x64 … Read more
Yup, I think you understand what’s going on. SetWindowsHookEx() requires a valid module handle, and verifies it, but it doesn’t actually use it when you set a low-level hook. You just need a valid handle, it doesn’t matter which specific one. Calling LoadLibrary(“user32.dll”) is a good way to get a handle, that DLL will always … Read more
No. The C# specification rigidly defines that int is an alias for System.Int32 with exactly 32 bits. Changing this would be a major breaking change.
That message isn’t actually an error – it’s just a warning that the file in question isn’t of the right architecture (e.g. 32-bit vs 64-bit, wrong CPU architecture). The linker will keep looking for a library of the right type. Of course, if you’re also getting an error along the lines of can’t find lPI-Http … Read more
This is known to work on Ubuntu 16.04 through 22.04: sudo apt install gcc-multilib g++-multilib Then a minimal hello world: main.c #include <stdio.h> int main(void) { puts(“hello world”); return 0; } compiles without warning with: gcc -m32 -ggdb3 -O0 -pedantic-errors -std=c89 \ -Wall -Wextra -pedantic -o main.out main.c And ./main.out outputs: hello world And: file … Read more
If you’re using .NET 4.0, it’s a one-liner for the current process: Environment.Is64BitProcess Reference: Environment.Is64BitProcess Property (MSDN)
If you have a large array of numbers, then go with the smallest size that works. It will be more efficient to work with an array of 16 bit shorts than 32 bit ints since you get twice the cache density. The cost of any sign extension the CPU has to do to work with … Read more
According to an official email sent by the Google Play Team, the action required is: If you haven’t yet, we encourage you to begin work for the 64-bit requirement as soon as possible. Many apps are written entirely in non-native code (e.g. the Java programming language or Kotlin) and will not need code changes. Please … Read more
QEMU and binfmt support light the way 🙂 https://github.com/microsoft/wsl/issues/2468#issuecomment-374904520 After reading that the WSLInterop between WSL and Windows processes used binfmt, I was tinkering with QEMU to try some ARM development, and incidentally discovered how to get 32-bit support working. Edit: requires “Fall Creators Update”, 1709, build 16299 or newer Install qemu and binfmt config: … Read more
