Package: r-cran-curl Version: 0.9.6-1 Severity: important Tags: upstream patch
r-cran-curl fails to build on big endian architectures. Here are the relevant parts of the build log: | gcc -std=gnu99 -I/usr/share/R/include -DNDEBUG -fpic -g -O2 -fstack-protector-strong -Wformat -Werror=format-security -Wdate-time -D_FORTIFY_SOURCE=2 -g -c curl.c -o curl.o | curl.c: In function 'rcurl_fgetc': | curl.c:138:38: warning: implicit declaration of function 'BSWAP_32' [-Wimplicit-function-declaration] | return rcurl_read(&x, 1, 1, con) ?
