I'm trying to build lsquic

I tried two ways

  1. As it is written in your guide
  2. As shown in this example https://github.com/dtikhonov/lsquic-tutorial/blob/master/CMakeLists.txt

My test CMakeLists.txt

CMAKE_MINIMUM_REQUIRED(VERSION 3.5)
PROJECT(lsquic-tutorial C)

ADD_SUBDIRECTORY(boringssl)

INCLUDE_DIRECTORIES(boringssl/include)
INCLUDE_DIRECTORIES(lsquic/include)
INCLUDE_DIRECTORIES(lsquic/src/liblsquic)
ADD_SUBDIRECTORY(lsquic/src/liblsquic)

wsl output:

I have latest versions of boringssl and lsquic

My perl version: v5.34.0

perl -v

This is perl 5, version 34, subversion 0 (v5.34.0) built for x86_64-linux-gnu-thread-multi
(with 60 registered patches, see perl -V for more detail)

The perl script src/liblsquic/gen-verstr.pl will generate the wrong code under the WSL environment. The reason is the script cannot parse the header file include/libquic.h correctly due to the crlf line ending which is caused by Windows. Thus I use a tool named dos2unix to convert header file's format to unix format, and it works. Here's the correctly generated file src/liblsquic/lsquic_versions_to_string.c:

/*

#include <assert.h>
#include <string.h>

#include "lsquic.h"

struct lsquic_engine;

static const char *const versions_to_string[ 1 << N_LSQVER ] = {
    [0] = "",
    [(1<<LSQVER_043)] = "43",
    [(1<<LSQVER_046)] = "46",
    [(1<<LSQVER_043)|(1<<LSQVER_046)] = "43,46",
};

lsquic_get_alt_svc_versions (unsigned versions)

    /* Limit to versions in versions_to_string: */
    versions &= ((1<<LSQVER_043)|(1<<LSQVER_046));
    return versions_to_string[ versions ];
}
