From: Uwe Hermann Date: Fri, 3 May 2013 12:49:21 +0000 (+0200) Subject: Main header is now. X-Git-Tag: libsigrokdecode-0.2.0~5 X-Git-Url: https://sigrok.org/gitweb/?p=libsigrokdecode.git;a=commitdiff_plain;h=c1f86f02a149f46609273e1bd5b42696d544727a Main header is now. This matches the convention used in libsigrok. Potential other headers might end up in libsigrokdecode/, but only libsigrokdecode.h is meant to be #included by frontends directly. --- diff --git a/.gitignore b/.gitignore index da30138..b812ba6 100644 --- a/.gitignore +++ b/.gitignore @@ -17,7 +17,7 @@ map missing stamp-h1 autostuff/ -sigrokdecode.h +libsigrokdecode.h ChangeLog INSTALL diff --git a/Makefile.am b/Makefile.am index e6f2ced..d3f91b8 100644 --- a/Makefile.am +++ b/Makefile.am @@ -31,8 +31,9 @@ libsigrokdecode_la_CPPFLAGS = $(CPPFLAGS_PYTHON) \ -DDECODERS_DIR='"$(DECODERS_DIR)"' libsigrokdecode_la_LDFLAGS = $(SRD_LIB_LDFLAGS) $(LDFLAGS_PYTHON) -include_HEADERS = sigrokdecode.h -noinst_HEADERS = sigrokdecode-internal.h +library_includedir = $(includedir)/libsigrokdecode +library_include_HEADERS = libsigrokdecode.h +noinst_HEADERS = libsigrokdecode-internal.h pkgconfigdir = $(libdir)/pkgconfig pkgconfig_DATA = libsigrokdecode.pc diff --git a/configure.ac b/configure.ac index 5431835..3ed527f 100644 --- a/configure.ac +++ b/configure.ac @@ -148,7 +148,7 @@ AC_SUBST(SRD_PACKAGE_VERSION_MICRO) AC_SUBST(SRD_PACKAGE_VERSION) AC_CONFIG_FILES([Makefile - sigrokdecode.h + libsigrokdecode.h libsigrokdecode.pc contrib/Makefile decoders/Makefile diff --git a/controller.c b/controller.c index e023b71..c9825b9 100644 --- a/controller.c +++ b/controller.c @@ -18,8 +18,8 @@ * along with this program.
