在Cygwin下安装SCTK 2.4.0的sclite时遇C++模板参数无效错误

Hey there! I’ve dealt with similar compatibility hiccups between old speech toolkit code and modern Cygwin compilers, so let’s work through this error step by step.

What’s Likely Causing This? #

The error points to outdated C++ template syntax that’s no longer accepted by newer versions of GCC (the default compiler in Cygwin). SCTK 2.4.0 is a bit long in the tooth, so its code might not align with stricter C++ standards enforced by recent GCC releases.

Step-by-Step Solutions #

1. Force Compilation with an Older C++ Standard

Newer GCC versions default to stricter standards like C17 or C20, which reject the redundant template qualifier in Filter::Filter*. Try forcing the compiler to use an older, more permissive standard:

• Open the main Makefile (or the specific Makefile for sclite)
• Look for lines defining CXXFLAGS and add -std=gnu++98 to the list of flags. For example:

  CXXFLAGS = -m64 -std=gnu++98 -O2
  

• Save the file, then clean previous build artifacts:

  make clean
  

• Re-run your 64-bit compile command:

  make all CC=gcc CXX=g++ CFLAGS="-m64" CXXFLAGS="-m64 -std=gnu++98"
  

2. Fix the Redundant Template Qualifier Directly

If the standard flag doesn’t work, you can edit the problematic code to remove the redundant scope qualifier:

• Locate the file mentioned in the error (the In file inc... line will tell you which header/source file to check)
• Find the line where Filter::Filter* is used as a template argument. Change it to just Filter*—the Filter:: prefix is unnecessary here and confuses modern compilers.
• Save the file, run make clean, then recompile with your usual 64-bit flags.

3. Verify Cygwin Dependencies Are Fully Installed

Double-check that you have all required build tools installed in Cygwin:

• Run gcc --version and g++ --version to confirm both compilers are present
• Ensure packages like make, libncurses-devel, and git (if you cloned the repo) are installed via the Cygwin setup.exe

Quick Note #

Since you already got past the file format issue using the 64-bit compile method, sticking with those -m64 flags alongside the fixes above should get you over this hump. If you hit other minor syntax errors, they’ll likely follow the same pattern—outdated code that needs small tweaks for modern compilers.
