From 8af6b087e076114502656baf58839494bb373530 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Petr=20=C5=A0tetiar?= Date: Mon, 10 Oct 2022 07:36:56 +0200 Subject: [PATCH] curl-wolfssl.m4: error out if wolfSSL is not usable MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit When I explicitly declare, that I would like to have curl built with wolfSSL support using `--with-wolfssl` configure option, then I would expect, that either I endup with curl having that support, for example in form of https support or it wouldn't be available at all. Downstream projects like for example OpenWrt build curl wolfSSL variant with `--with-wolfssl` already, but in certain corner cases it does fail: configure:25299: checking for wolfSSL_Init in -lwolfssl configure:25321: x86_64-openwrt-linux-musl-gcc -o conftest [snip] In file included from target-x86_64_musl/usr/include/wolfssl/wolfcrypt/dsa.h:33, from target-x86_64_musl/usr/include/wolfssl/wolfcrypt/asn_public.h:35, from target-x86_64_musl/usr/include/wolfssl/ssl.h:35, from conftest.c:47: target-x86_64_musl/usr/include/wolfssl/wolfcrypt/integer.h:37:14: fatal error: wolfssl/wolfcrypt/sp_int.h: No such file or directory #include ^~~~~~~~~~~~~~~~~~~~~~~~~~~~ compilation terminated. and in the end thus produces curl without https support: curl: (1) Protocol "https" not supported or disabled in libcurl So fix it, by making the working wolfSSL mandatory and error out in configure step when that's not the case: checking for wolfSSL_Init in -lwolfssl... no configure: error: --with-wolfssl but wolfSSL was not found or doesn't work References: https://github.com/openwrt/packages/issues/19005 References: https://github.com/openwrt/packages/issues/19547 Signed-off-by: Petr Štetiar Closes #9682 --- m4/curl-wolfssl.m4 | 3 ++- 1 file changed, 2 insertions(+), 1 deletion(-) diff --git a/m4/curl-wolfssl.m4 b/m4/curl-wolfssl.m4 index e05ad26bc9..d66c97935e 100644 --- a/m4/curl-wolfssl.m4 +++ b/m4/curl-wolfssl.m4 @@ -154,7 +154,8 @@ if test "x$OPT_WOLFSSL" != xno; then AC_MSG_NOTICE([Added $wolfssllibpath to CURL_LIBRARY_PATH]) fi fi - + else + AC_MSG_ERROR([--with-wolfssl but wolfSSL was not found or doesn't work]) fi fi dnl wolfSSL not disabled
