From 4159566e56a8521143c22b611e28157e958d1299 Mon Sep 17 00:00:00 2001 From: Alex Richardson Date: Wed, 3 Mar 2021 13:53:30 +0000 Subject: [PATCH] Fix capsicum-test build with GCC Apparently GCC defines NULL to 0 in C++11 mode (instead of nullptr), so this causes the following error: ``` In file included from capsicum-test.h:15, from capsicum-test.cc:1: gtest-1.10.0/include/gtest/gtest.h: In instantiation of 'testing::AssertionResult testing::internal::CmpHelperNE(const char*, const char*, const T1&, const T2&) [with T1 = long int; T2 = procstat*]': capsicum-test.cc:75:3: required from here gtest-1.10.0/include/gtest/gtest.h:1621:28: error: ISO C++ forbids comparison between pointer and integer [-fpermissive] 1609 | if (val1 op val2) {\ | ~~~~~~~~~~~~ ...... 1621 | GTEST_IMPL_CMP_HELPER_(NE, !=); gtest-1.10.0/include/gtest/gtest.h:1609:12: note: in definition of macro 'GTEST_IMPL_CMP_HELPER_' 1609 | if (val1 op val2) {\ | ^~ ``` Fix this by using nullptr directly.
